Summary:
Profiler side of memory snapshot.
1. Add API to actually do snapshot when client interface is called
2. Add ifdefs to builds so that kineto hooks snapshot correctly.
Design Philosophy: There is one interesting part of this implementation and it is during export. For export we are callign the python impl of the export rather than CPP even though we are already in CPP. This is because it is better to simply have one path of export rather than 2. Personally, I want there to be parity between auto-trace and on-demand so it if we can limit the side paths then we will have an easier time maintaining this relationship

Summary:
We need to properly fakify torchbind objects, including the ones in graph module attributes, so the resgitered fake implementation works properly.
- _fakify_script_objects in `compile_fx`
- Allow fake torchbind objects in `torchbind_constants`
Remove `node.meta["unbacked_bindings"]` for `aot_compile` in `compile_fx`. Otherwise `ShapeProp` will fail when trying to resolve the `unbacked_bindings` of `with_effect` tokens.
Update `sigrid_transforms_test` to use the latest `torch._inductor.aot_compile` API.
Add a test for `Fakify torchbind objects in compile_fx and add tests for SigridTransformsInstanceTorchBind` in `e2e_test`.
Test Plan:
```
buck run //caffe2/torch/fb/sparsenn:sigrid_test -- -r test_transform_torch_bind
buck run //sigmoid/inference/test:e2e_test_cpu -- -r SigridTransforms

This change fixes the RUNPATH of installed c++ tests so that the linker can find the shared libraries they depend on.
For example, currently:
```bash
venv/lib/python3.10/site-packages/torch $ ./bin/test_lazy
./bin/test_lazy: error while loading shared libraries: libtorch.so: cannot open shared object file: No such file or directory
```

Sometimes, it could be difficult to write a fake class e.g. when the original implementation is using some third-party libraries or users are certain that the class is safe to trace with the real object.
This PR allows user to specify their intention by implementing a "safe_to_trace_with_real_obj" method on their script class.
Test Plan:
`pytest test/export/test_torchbind.py -k safe`

As titled. Previously, __obj_flatten__ can run in a fake tensor mode, e.g. in process_input of aot_autograd, which is surrounded by a fake tensor mode. This causes the tensor ops inside __obj_flatten__ to run under fake tensor mode. However, tensors inside of script obejct are real tensors, this causes the fake tensor mode to error out saying that we need to first fakify fall the tensors (because allow_non_fake_inputs is set to True).
In this PR, we disable all the dispatch modes when running to_fake_obj.
Note that, the output of `__obj_flatten__` will be fakified and filled inside of the corresponding FakeScriptObject. So during traicng, we'll be using FakeScriptObject that has fake tensor contents.
Test Plan:
Add a new test: pytest test/export/test_torchbind.py -k test_compile_tensor_op_in_tensor_flatten

This PR does two things:
1. it duplicates the fake script object because aot_export trace the program twice. The result of tracing in the first time would cause the tracing result of second time be wrong.
2. Also add a new test for methods that return constant outputs. Before the PR, there's is no meta["val"] for these nodes because fx won't track these constants. We still need to preserve these constant return operators in the graph because torchbind objects are stateful and deleting it would remove the implicit state mutation inside of the object.

Adds `C10_UBSAN_ENABLED` macro and use it to disable `SymIntTest::Overflows` (fails under `signed-integer-overflow` UBSAN check).
Also cleans up UBSAN guard in `jit/test_misc.cpp` to use `C10_UBSAN_ENABLED` and the existing `C10_ASAN_ENABLED` instead of locally defining `HAS_ASANUBSAN`.
> NOTE: This should fix `SymIntTest::Overflows` failing under ubsan in fbcode too...

This PR only adds abstract class registration logic without touching existing tests so they still trace with real script object. The added tests are only for registration APIs and test error messages.
Our design is that the abstract implementation should be in Python. This is much better in terms of usability. But this also has implications for custom op that takes script object as input, which is detailed later in this stack.

Do not run test ConstantPropagation.CustomClassesCanBePropagated on a platform where QNNPACK is not supported.
For example, this test fails on M1 Mac because QNNPACK is not supported on M1 Mac:
[----------] 1 test from ConstantPropagation
[ RUN ] ConstantPropagation.CustomClassesCanBePropagated
unknown file: Failure
as described in more details in the issue #88613.
After the PR, test passes successfully as below:
[----------] 1 test from ConstantPropagation
[ RUN ] ConstantPropagation.CustomClassesCanBePropagated
[ OK ] ConstantPropagation.CustomClassesCanBePropagated (0 ms)
[----------] 1 test from ConstantPropagation (0 ms total)

Recently we made it possible to serialize ExportedPrograms with fake parameters/buffers/etc.
The serialization regime was kind of whacky; basically we serialized a stub and reassembled the FakeTensor using metadata that we had stashed elsewhere in the Graph state.
This was bad for a few reasons:
- Storing the metadata separately from the actual serialized object caused situations where you could have one but not the other. An example case is if you had a FakeTensor contained inside a TorchBind object—there was no obviously place to store the metadata for this. This actually happens—TensorQueue in fbgemm does this.
- It created an annoying cycle: we had to deserialize the Graph's tensor metadata in order to deserialize (potentially faked) constants, but we need constants in order to deserialize the Graph.
This fixes all that. The basic idea is to patch the reducer function for FakeTensor at serialization time, and serialize a copy of the FakeTensor metadata. We already are policing BC for the TensorMeta schema struct so it's not a net increase in the BC surface.
As a bonus, I fixed a weird bug with torchbind tracing where we were accidentally reinterpreting a torch.ScriptObject as a torch.ScriptModule (which was the root cause of some weird behavior @bahuang was seeing last week).

This PR adds the bare minimum functionality to get torchbind working in an e2e testable way on PT2.
It implements:
* ProxyTensor support
* Simple torch.export support (proxytensor-only path, e.g. non-strict).
* add some tests exercising the path.
Because all this is not fully baked, I hide the functionality behind a feature flag (`enable_torchbind_tracing()`) so it does not affect regular users for now.
Still on the agenda:
* Dynamo support
* Actual FakeMode support
* Mutability support
Hoping to get this first bit in as a standalone, as it will unblock some more extensive experimentation/testing going on internally.

Summary:
Move the profiler's Approximate Clock from libtorch to libc10. The main reason is to allow c10 features to get time.
The clock is using TSC when available for performance. CUDA Caching Allocator's implementation of memory snapshot will add the timestamps to memory events with this same clock in subsequent diff.
