Related: #148920
This PR:
* Provides a helper `install_cpp_extension(extension_root)` for building C++ extensions. This is intended to be used in `TestMyCppExtension.setUpClass()`
* Updates libtorch_agnostic tests to use this
* Deletes preexisting libtorch_agnostic tests from `test/test_cpp_extensions_aot.py`
* Fixes `run_test.py` to actually run tests in `test/cpp_extensions/libtorch_agnostic_extension/test/test_libtorch_agnostic.py` to avoid losing coverage. This wasn't being run due to logic excluding tests that start with "cpp"; this is fixed now
After this PR, it is now possible to run:
```
python test/cpp_extensions/libtorch_agnostic_extension/test/test_libtorch_agnostic.py
```
and the test will build the `libtorch_agnostic` extension before running the tests.

This is a follow-up PR of the reverted one https://github.com/pytorch/pytorch/pull/147019 :
Modified TorchInductor’s autotuning flow so that each best_config JSON file also includes the Triton “base32” (or base64) cache key.
Motivation
Debugging & Analysis: With this change, we can quickly identify which compiled binary and IRs belongs to a given best config.
The impact is minimal since it is only an extra field in .best_config. It can help advanced performance tuning or kernel-level debugging.
Also, since Triton already stores cubin/hsaco in its cache, developers/researchers can avoid to set store_cubin = True since they can get the cubin/hsaco in the Triton cache and with the code provided in this PR, they can easily match the best_config with the right Triton cache directory for the "best" kernel.

There are only 118 failures atm, mark them all with xfail to avoid new regressions
Add `xfail_if_mps_unimplemented` decorator to distinguish between tests that call unimplemented eager op vs ones that fail for some other reason.
Added `aten._scaled_dot_product_attention_math_for_mps` fallback to make test behavior consistent between MacOS-15 (where falback is in place) and MacOS-14
Weird MacOS-14 specific skips:
- test_torchinductor.py::GPUTests::test_cat_extern_kernel_mps
- test_torchinductor.py::GPUTests::test_sort_transpose_mps (likely an eager bug)
- test_torchinductor.py::GPUTests::test_unaligned_input_mps
Numerous MacOS-13 skips, including few eager hard crashes, for example running `test_torchinductor.py::GPUTests::test_scatter5_mps` causes

Enable TD on distributed cpu, I think the only reason it's not is because I forgot to enable it
Get rid of some of the statements that are no ops:
* asan uses default shard
* nogpu got moved to periodic
* no windows cuda testing anymore
Only thing on pull and trunk that doesn't use TD is dynamo_wrapped but I think it's fast enough to be ok for now, we can take another look after this

This PR adds two main parts:
- shim.h stable C APIs into torch::Library APIs
- a higher level API in torch/csrc/stable/library.h that calls into this shim.h + otherwise is self contained
Goal: custom kernel writers should be able to call the apis in the directories above in order to register their library in a way that allows their custom extension to run with a different libtorch version than it was built with.
Subplots resolved:
- Do we want a whole separate StableLibrary or do we want to freeze torch::Library and add `m.stable_impl(cstring, void (*fn)(void **, int64_t, int64_t)` into it
- Yes, we want a separate StableLibrary. We cannot freeze Library and it is NOT header only.
- Should I use unint64_t as the common denominator instead of void* to support 32bit architectures better?
- Yes, and done
- Should I add a stable `def` and `fragment` when those can be done in python?
- I think we do want these --- and now they're done
- Where should library_stable_impl.cpp live? -- no longer relevant
- I need some solid test cases to make sure everything's going ok. I've intentionally thrown in a bunch of random dtypes into the signature, but I still haven't tested returning multiple things, returning nothing, complex dtypes, etc.
- Have since tested all the torch library endpoints. the others can be tested in a followup to separate components that need to be in shim.h vs can be added later

The distributed tests are executed once for each backend and for each init method.
`$TEST_REPORT_SOURCE_OVERRIDE` is used such that test results from different backends are stored in different files.
The same needs to be done for the init method.
Move the setting of the variable into `test_distributed` and incorporate the init method into the name.

When the test times are generated, it doesn't know what the build environment is because it's an environment variable. But when we index into the test times, we (previously) didn't know what the job name is. These are usually the same but sometimes they're different and when they're different it ends up using default, which can have unbalanced sharding
I think job name was added at some point to most of the CI environments but I didn't realize, so we can now update this code to use the job name instead so the generation and the indexing match
also upload stats workflow for mps
Checked that inductor_amx doesn't use default

Periodically run testsuite for s390x
**Dependencies update**
Package z3-solver is updated from version 4.12.2.0 to version 4.12.6.0. This is a minor version update, so no functional change is expected.
The reason for update is build on s390x. pypi doesn't provide binary build for z3-solver for versions 4.12.2.0 or 4.12.6.0 for s390x. Unfortunately, version 4.12.2.0 fails to build with newer gcc used on s390x builders, but those errors are fixed in version 4.12.6.0. Due to this minor version bump fixes build on s390x.
```
# pip3 install z3-solver==4.12.2.0

**Python paths update**
On AlmaLinux 8 s390x, old paths:
```
python -c 'from distutils.sysconfig import get_python_lib; print(get_python_lib())'
/usr/lib/python3.12/site-packages
```
Total result is `/usr/lib/python3.12/site-packages/torch;/usr/lib/python3.12/site-packages`
New paths:
```
python -c 'import site; print(";".join([x for x in site.getsitepackages()] + [x + "/torch" for x in site.getsitepackages()]))'
/usr/local/lib64/python3.12/site-packages;/usr/local/lib/python3.12/site-packages;/usr/lib64/python3.12/site-packages;/usr/lib/python3.12/site-packages;/usr/local/lib64/python3.12/site-packages/torch;/usr/local/lib/python3.12/site-packages/torch;/usr/lib64/python3.12/site-packages/torch;/usr/lib/python3.12/site-packages/torch
```
```
# python -c 'import torch ; print(torch)'
<module 'torch' from '/usr/local/lib64/python3.12/site-packages/torch/__init__.py'>
```
`pip3 install dist/*.whl` installs torch into `/usr/local/lib64/python3.12/site-packages`, and later it's not found by cmake with old paths:

**Builders availability**
Build took 60 minutes
Tests took: 150, 110, 65, 55, 115, 85, 50, 70, 105, 110 minutes (split into 10 shards)
60 + 150 + 110 + 65 + 55 + 115 + 85 + 50 + 70 + 105 + 110 = 975 minutes used. Let's double it. It would be 1950 minutes.
We have 20 machines * 24 hours = 20 * 24 * 60 = 20 * 1440 = 28800 minutes
We currently run 5 nightly binaries builds, each on average 90 minutes build, 15 minutes test, 5 minutes upload, 110 minutes total for each, 550 minutes total. Doubling would be 1100 minutes.
That leaves 28800 - 1100 = 27700 minutes total. Periodic tests would use will leave 25750 minutes.
Nightly binaries build + nightly tests = 3050 minutes.
25750 / 3050 = 8.44. So we could do both 8 more times for additional CI runs for any reason. And that is with pretty good safety margin.
**Skip test_tensorexpr**
On s390x, pytorch is built without llvm.
Even if it would be built with llvm, llvm currently doesn't support used features on s390x and test fails with errors like:
```
JIT session error: Unsupported target machine architecture in ELF object pytorch-jitted-objectbuffer
unknown file: Failure
C++ exception with description "valOrErr INTERNAL ASSERT FAILED at "/var/lib/jenkins/workspace/torch/csrc/jit/tensorexpr/llvm_jit.h":34, please report a bug to PyTorch. Unexpected failure in LLVM JIT: Failed to materialize symbols: { (main, { func }) }
```
**Disable cpp/static_runtime_test on s390x**
Quantization is not fully supported on s390x in pytorch yet.

Getting tested with ao, but now there is a real test i added.
## What does this PR do?
We want to allow custom PyTorch extensions to be able to build one wheel for multiple Python versions, in other words, achieve python agnosticism. It turns out that there is such a way that setuptools/Python provides already! Namely, if the user promises to use only the Python limited API in their extension, they can pass in `py_limited_api` to their Extension class and to the bdist_wheel command (with a min python version) in order to build 1 wheel that will suffice across multiple Python versions.
Sounds lovely! Why don't people do that already with PyTorch? Well 2 things. This workflow is hardly documented (even searching for python agnostic specifically does not reveal many answers) so I'd expect that people simply don't know about it. But even if they did, _PyTorch_ custom Extensions would still not work because we always link torch_python, which does not abide by py_limited_api rules.
So this is where this PR comes in! We respect when the user specifies py_limited_api and skip linking torch_python under that condition, allowing users to enroll in the provided functionality I just described.
## How do I know this PR works?
I manually tested my silly little ultra_norm locally (with `import python_agnostic`) and wrote a test case for the extension showing that
- torch_python doesn't show up in the ldd tree
- no Py- symbols show up
It may be a little confusing that our test case is actually python-free (more clean than python-agnostic) but it is sufficient (and not necessary) towards showing that this change works.

This allows one to do something like that
```python
import torch
x = torch.ones(10, device="mps")
m = torch.mps._compile_shader("""
kernel void foo(device float* x, uint idx [[thread_position_in_grid]]) {
x[idx] += idx;
}
")
m.foo(x)
```
And in general enables writing custom operators using Metal shaders purely in Python

So I found this utility by accident, trying to find how many html files we have in the repo so I could convert them to markdown
Turns out we package some html and js files in pytorch to visualize torchscript models. This seems kinda strange, probably shouldn't be in core, I removed the tests I could find. Maybe some internal tests will break but considering torchscript is being superseded might make sense to do this
Last time there was a meaningful update to the test for this file was about 2 years ago by @digantdesai since then it's a bunch of routine upgrades
It seems like this package is unused https://github.com/search?type=code&auto_enroll=true&q=torch.utils.model_dump&p=1 I skimmed through 5 pages of these and the only time this shows up in code search is when someone is either cloning pytorch or checking in their venv into github

Remove most references to rockset:
* replace comments and docs with a generic "backend database"
* Delete `upload_to_rockset`, so we no longer need to install the package.
* Do not upload perf stats to rockset as well (we should be completely on DynamoDB now right @huydhn?)
According to VSCode, it went from 41 -> 7 instances of "rockset" in the repo

This is a utility to aid the torch.compile debugging. You provide a function that returns True on success, False on failure, or do something out of process and run bisect_helper `good | bad`.
The bisector will first go through backends - `eager`, `aot_eager`, `aot_eager_decomp_partition`, `inductor` to find the first failing backend. Then, it will go through subsystems within the backend - currently limited but could be expanded - and try to find the first subsystem for which disabling fixes the problem. Once it has found the failing subsystem, it will find the number of times the subsystem is applied, and then bisect through it.
An example usage of how to hook it up for aot_eager_decomp_partition and decomposition subsystem is :
```
from torch._inductor.bisect_helper import BisectionManager
if op in CURRENT_DECOMPOSITION_TABLE:
if BisectionManager.disable_subsystem("aot_eager_decomp_partition", "decomposition", lambda: repr(op)):
return NotImplemented
```
Once it has discovered the problematic change, it will print out the associated debug info, and you can set the same limits with `TORCH_BISECT_BACKEND` `TORCH_BISECT_SUBSYSTEM` and `TORCH_BISECT_MAX`.
We could add further options as an automated way of going through a check list for checking divergence - e.g., the mode to emulate amp casts.

Some of the tests are decorated with `@expectedFailureMPS` for various reasons. Either that the op is not implemented, or that the outputs do not align. Those tests that contain differing results should be investigated further to rule out any live bugs.

It is possible to write to Meta's internal in-memory database Scuba via the Scribe Graph API: https://www.internalfb.com/intern/wiki/Scribe/users/Knowledge_Base/Interacting_with_Scribe_categories/Graph_API/ This is currently being used by pytorch/benchmark repo to upload torchbench performance results.
I want to make this API generally available to all jobs running on CI in a semi-trusted context. To talk to Scribe, you need a secret access token. I have initially configured an environment prod-branch-main which contains `SCRIBE_GRAPHQL_ACCESS_TOKEN`, and switched a single class of jobs (linux-test) to use this environment when they are running on the main branch. Because we require approvals for running CI on untrusted contributions, we could potentially allow all jobs to run in this environment, including jobs on PRs, but I don't need this for my use case (per-PR benchmark result reporting, and miscellaneous statistics on main.)
If this works, I'll push out this environment to the rest of our test jobs.

Add a new label `ci-test-showlocals` and add it to test config filter.
If the PR is labeled with `ci-test-showlocals` or "ci-test-showlocals"
present in the PR comment, the test config filter will set a environment
variable `TEST_SHOWLOCALS`. Then `pytest` will show local variables on
failures for better debugging.

As per the title, add argument `--locals` for `unittest` and `--showlocals --tb=long` for `pytest` in CI.
Some failures cannot be reproduced on the local machine but exist on cloud CI. This change allows us to investigate the test failure more easily.

Rerun the failing test singly with the env var set. If it succeeds, start a new process without the cpp stack traces env var
We don't want to waste time generating these if we don't have to
They can also show up in assertion errors, which may cause unexpected failures if a test wants to check these
Adds new --rs (run single) to be used the same way --scs and --sc are. It will only run the single test in the step current file
https://hud.pytorch.org/pytorch/pytorch/pull/129004?sha=2c349d3557d399020bf1f6a8b7045e2e4957ba46 has some examples of logs
In the above:
* test_checkpoint_valid failed, then passed in another subprocess. The testing continued in a different new subprocess from the test right after it (test_checkpointing_without_reentrant_early_free)
* test_format_traceback_short failed consistently, but it continued to run because keep-going was set

Do not inherit parser from common_utils
* I don't think we use any variables in run_test that depend on those, and I think all tests except doctests run in a subprocess so they will parse the args in common_utils and set the variables. I don't think doctests wants any of those variables?
Parse known args, add the extra args as extra, pass the extra ones along to the subprocess
Removes the first instance of `--`
I think I will miss run_test telling me if an arg is valid or not

Looking at the unrelated Windows timeout failure on https://github.com/pytorch/pytorch/pull/125199, it looks like we don't have a timeout value set for C++ tests atm. In this case, a C++ test on Windows timed out after 2+ hours.
