After the UT suite moved to `MultiProcContinuousTest`, `skipIfRocm` decorator started failing rather than skipping UTs because now we spawn multiple threads before the skip decorator is taken into account and the skip decorator was raising an exception to exit the process. But, the parent process treated the child process exiting as a crash rather than a skip. Additionally, in `MultiProcContinuousTest`, if one UT fails all subsequent ones are also skipped which makes sense since there's one setup for the entire suite. However, this showed up as many failing/skipped UTs in the parity.
I added multiprocess version of skip decorators for ROCm, including, `skip_if_rocm_arch_multiprocess` and
`skip_if_rocm_ver_lessthan_multiprocess`. These are needed as symmetric memory feature is only supported on MI300 onwards and we need to skip them for other archs and some UTs only work after ROCm7.0.

In this PR we will port all distributed pipeline test files.
We could enable Intel GPU with following methods and try the best to keep the original code styles:
1. instantiate_device_type_tests()
2. use "torch.accelerator.current_accelerator()" to determine the accelerator backend
3. use "requires_accelerator_dist_backend()" to replace requires_nccl()
4. use "get_default_backend_for_device()" to get backend
5. enabled XPU for some test path
6. add TEST_MULTIACCELERATOR in common_utils for all backend.

Automatically replaces split with rsplit when relevant and only performs the split up to the first ( or last value). This allows early return of the split function and improve efficiency.

The current implementation assumes test functions are resolved as test_module.TestClass.test_fn, however this would not work for modules nested in directories e.g. inductor.test_torchinductor.TestClass.test_fn

This would allow me to enable more opinfo tests against MPS device eventually and supposed to be a very simple test, but actually required minor adjustments to lots of test files, namely:
- Introduce `all_mps_types_and` that is very similar to `all_types_and`, but skips `float64`
- Decorate lots of tests with `@dtypesIfMPS(*all_mps_types())`
- Skip `test_from_dlpack_noncontinguous` as it currently crashes (need to be fixed)
- Add lots of `expectedFailureIfMPS`
- Delete all `@onlyNativeDeviceTypesAnd("mps")`
<sarcasm> I love how well documented this variable are </sarcasm>

Hi team,
Please help review this patch.
This PR https://github.com/pytorch/pytorch/pull/150370 tried to fix the "Empty C Call Queue" problem on Python 3.12. It added C calls for each starting Python event with a callable.
I found the root cause is not that we cannot get C function frames by `PyFrame_GetBack` when PythonTracer is filling start frames, but the c call event loss problem bug on Python 3.12.0-3.12.4. And that problem was fixed by 257c413cd1 on 3.12.5.
So I think the https://github.com/pytorch/pytorch/pull/150370 cannot fix the problem, this patch reverts the change of it.
There are solutions to fix the problem correctly, such as we can add a new monitoring callback to compensate call events of methods with C function or we can override the callback registered by `PyEval_SetProfile`. These solutions may make the code hard to maintain.
~~Since upgrading the micro version of Python is not difficult for users, we can just ignore C functions and suggest user upgrade.~~

Otherwise it turns test into a trivial one(that always succeeds), as following example demonstrates
```python
import torch
from torch.testing._internal.common_utils import serialTest, run_tests, TestCase
class MegaTest(TestCase):
@serialTest
def test_foo(self):
if hasattr(self.test_foo, "pytestmark"):
print("foo has attr and it is", self.test_foo.pytestmark)
print("foo")
@serialTest()
def test_bar(self):
if hasattr(self.test_bar, "pytestmark"):
print("bar has attr and it is", self.test_bar.pytestmark)
print("bar")
if __name__ == "__main__":
run_tests()
```
That will print
```
test_bar (__main__.MegaTest.test_bar) ... bar has attr and it is [Mark(name='serial', args=(), kwargs={})]
bar
ok
test_foo (__main__.MegaTest.test_foo) ... ok
----------------------------------------------------------------------
Ran 2 tests in 0.013s
```
Added assert that arg is boolean in the decorator to prevent such silent skips in the future

Based on the [conversation](https://github.com/pytorch/pytorch/issues/121791), we plan to drop the "highest, high, medium" to represent fp32 internal computation data types . Instead, we will directly use the algorithm to represent it.
### Design Choice: Directly use algorithms name like "TF32", "BF16".
#### Pros
- The names are more informative. 'tf32' is more informative than a simple "high".
- Easier to extend new algorithm like `tf32x3`
#### Cons
- "HIGHEST, HIGH, MEDIUM" indicated the relative precision between different algorithms. However, we can have more documents to discuss them.
### We provide a layered structure for backends/operators.
('f32' is short for 'fp32_precision')
### We provide 3 fp32 compute precision can be set:
- **"ieee"**: Not allowed to use any other internal computation data types .
- **"tf32"**: Allowed to use tf32 as internal computation data types.
- **"bf16"**: Allowed to use bf16 as internal computation data types.
- **"none"**: Precision's are not set. Can be override by its father node.
### Overriding Precision Settings
Child node can be override by its father node if it is set to default.
For current default settings:
```
backend = generic, op = all, precision setting = none
backend = cuda, op = all, precision setting = none
backend = cuda, op = conv, precision setting = tf32
backend = cuda, op = rnn, precision setting = tf32
backend = cuda, op = matmul, precision setting = none
backend = matmul, op = all, precision setting = none
backend = matmul, op = conv, precision setting = none
backend = matmul, op = rnn, precision setting = none
backend = matmul, op = matmul, precision setting = none
```
- If the user set `torch.backends.mkldnn.fp32_precision="bf16"`, his child nodes `torch.backends.mkldnn.matmul.fp32_precision` / `torch.backends.mkldnn.conv.fp32_precision` / `torch.backends.mkldnn.rnn.fp32_precision` will also be override to "bf16".
- If the user set `torch.backends.fp32_precision="bf16"`, `torch.backends.mkldnn.fp32_precision` and his child nodes will also we override to "bf16".
### Backward Compatible
Since new API allow user to have more fine-grained control. There will be some conflict. For example, previous `torch.backends.cudnn.allow_tf32` are not enough to represent the status for `torch.backends.cudnn.rnn.fp32_precision="ieee"` and `torch.backends.cudnn.conv.fp32_precision="tf32"`. Therefore, our goal for backward compatible is
- If the user only uses previous APIs, it will work as previous expectations.
- If the user use **new** API to change the status to an **un-representable** status for old API, and try to access the status by **old** API. We will raise Runtime Error and point the document for user.
### Test Plan
```
python test/test_cuda.py -k test_fp32_precision_with_tf32
python test/test_cuda.py -k test_fp32_precision_with_float32_matmul_precision
python test/test_cuda.py -k test_invalid_status_for_legacy_api
python test/test_mkldnn.py -k test_mlkdnn_get_set
python test/test_mkldnn.py -k test_generic_precision
python test/test_mkldnn.py -k test_invalid
python test/test_mkldnn.py -k test_default_use_parent
```

There are a few considerations here:
1. A user might want to modify the cudaGraph_t either during the stream capture or after the stream capture (but before instantiation). This draft implements modification after stream capture only, though support could be added for modification during stream capture by applying
https://github.com/pytorch/pytorch/pull/140979/files#diff-d7302d133bb5e0890fc94de9aeea4d9d442555a3b40772c9db10edb5cf36a35cR391-R404
2. Previously, the cudaGraph_t would be destroyed before the end of capture_end() unless the user had previously called enable_debug_mode(). There is no way to implement this correctly without removing this restriction, or forcing the user to always call enable_debug_mode(). However, enable_debug_mode() is a confusing API (despite being an instance method, it would modify a static global variable; thus, putting one CUDAGraph object into debug mode puts all of them into debug mode, which is not acceptable in my opinion). Therefore, I made enable_debug_mode() into a no-op. This means that the CPU memory usage will increase after this change. I think this is likely to be fine.
3. No python bindings yet. These should be easy to add. It is probably worthwhile to take some time to make sure that the returned cudaGraph_t can be converted into the cuda-python cudaGraph_t in a reasonable, hopefully type-safe, manner (but without making cuda-python a dependency of pytorch), since I imagine most users will use the pip cuda-python package to make modifications.
4. There are two foot guns:
a. The cudaGraph_t returned by raw_cuda_graph() is not owned by the user, so it will be destroyed once the owning CUDAGraph is destroyed (or calls reset()).
b. The following seuquence won't work as intended:
```
g = torch.cuda.CUDAGraph()
with torch.cuda.graph(g):
foo()
g.replay()
raw_graph = g.raw_cuda_graph()
modify(raw_graph)
g.replay()
```
This won't work because the user must call instantiate() again after modifying cudaGraph_t. You could add a "safety" mechanism by traversing the cudaGraph_t to create a hash and seeing if the hash changes between calls to replay(), but this is likely way too expensive.
I think these two foot guns are probably okay given that this a bit of an experts' API.

This PR is part of a series attempting to re-submit #134592 as smaller PRs.
In fx tests:
- Add and use a common raise_on_run_directly method for when a user runs a test file directly which should not be run this way. Print the file which the user should have run.
- Raise a RuntimeError on tests which have been disabled (not run)
- Remove any remaining uses of "unittest.main()""

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.
