MTIA device has its own Module in PyTorch now.
torch.mtia has following APIs similar to other backends. The lazy_init is also supported.
```
__all__ = [
"init",
"is_available",
"synchronize",
"device_count",
"current_device",
"current_stream",
"default_stream",
"set_stream",
"stream",
"device",
]
```
------------
For device management. We expand AccleratorHooksInterface to support generic device management and it can be used in both C++ and PyThon.
```
def _accelerator_hooks_device_count() -> _int: ...
def _accelerator_hooks_set_current_device(device_index: _int) -> None: ...
def _accelerator_hooks_get_current_device() -> _int : ...
def _accelerator_hooks_exchange_device(device_index: _int) -> _int : ...
def _accelerator_hooks_maybe_exchange_device(device_index: _int) -> _int : ...
```
---------
Adding get_device_module API to retrieve device modules for different device types.
```
def get_device_module(device: Optional[Union[torch.device, str]] = None)
```

This doesn't entirely fix the original problem that prompted this, but
it seems to just be getting stuck in export constraint formatting now
which seems like progress to me.

Python 3.12 changed a few things with how `_PyInterpreterFrame`s are allocated and freed:
- Frames are now required to be placed on the Python frame stack. In 3.11, we could allocate frames anywhere in memory. In 3.12, we now need to use `THP_PyThreadState_BumpFramePointerSlow`/`push_chunk`/`allocate_chunk`. This method of allocating/freeing frames is also compatible with 3.11.
- The eval frame function is now responsible for clearing the frame (see https://docs.python.org/3/whatsnew/changelog.html#id128, the point about "...which now clear the frame.")

1) Using items stored in torch._tensor_classes to check item passed from python side;
2) Add SparsePrivateUse1 in backend_to_string, layout_from_backend and check_base_legacy_new;
3) Using more general API to get python module name in get_storage_obj and get_name functions.

I was just playing around with improving the typing of symbolic_shapes. The PR is not "complete" but I in particular wanted to get feedback on whether or not people liked making ValueRanges Generic; it seems that distinguishing if you have an Expr ValueRange or a SympyBoolean ValueRange is a lot of trouble for downstream. Using TypeGuard, we can perform refinements on the generic parameter inside methods, although we still have to cast back to ValueRange[T] due to https://github.com/python/mypy/issues/14425#issuecomment-1914852707

Updates flake8 to v6.1.0 and fixes a few lints using sed and some ruff tooling.
- Replace `assert(0)` with `raise AssertionError()`
- Remove extraneous parenthesis i.e.
- `assert(a == b)` -> `assert a == b`
- `if(x > y or y < z):`->`if x > y or y < z:`
- And `return('...')` -> `return '...'`

To codegen deferred runtime asserts, I need to be able to convert sympy expressions back into regular Python expressions that I can put in FX graphs. This PR adds some of the machinery to do this: it adds a new sympy analysis that runs operations on all FX traceable operations that can also be run with plain Python int/float/bool/etc. It's tested by symbolic tracing through the analysis, and then testing that this traced graph gives the same result as running the Python analysis directly.

This PR also contains a basket of fixes that were turned up by now testing more arguments with SymInt. I fixed as many of the easy ones as I could easily get earlier in this stack and a bunch here, but there are some more annoying ones I xfailed.

`@classproperty` decorator adds another wrapper, so warning with default stacklevel (2) would always point to the wrapper implementation rather than at callee.
For example, before this change following code
```python
import torch
print(torch.FloatStorage.dtype)
```
will produce inactionable warning:
```
/Users/nshulga/git/pytorch/pytorch/torch/_utils.py:836: UserWarning: TypedStorage is deprecated. It will be removed in the future and UntypedStorage will be the only storage class. This should only matter to you if you are using storages directly. To access UntypedStorage directly, use tensor.untyped_storage() instead of tensor.storage()
return self.fget.__get__(instance, owner)()
```
But after the change warning turns into:
```
/Users/nshulga/test/bar.py:2: UserWarning: TypedStorage is deprecated. It will be removed in the future and UntypedStorage will be the only storage class. This should only matter to you if you are using storages directly. To access UntypedStorage directly, use tensor.untyped_storage() instead of tensor.storage()
print(torch.FloatStorage.dtype)
```

`install_config_module` makes a regular module into a ConfigModule with
extra methods defined on it. mypy thinks those extra methods (or module
functions) are undefined since it cannot analyze something so
dynamic. As a workaround, I've created a fake module that defines these
extra functions, which I import into the config modules during type
checking.
As part of this change, I've also added more types to config_utils.py
and enabled typechecking for torch/_dynamo/config.py.

Summary:
CUDA Graph does not work well with CUPTI teardown.
1) crashes on 1st lazy CUPTI re-init after teardown (CUDA 11)
2) crashes on 2nd non-lazy CUPTI re-init after teardown (CUDA 12)
Workaround: turn off CUPTI teardown when using CUDA Graphs completely.

This PR:
- Moves TrueDiv, LShift, RShift, IsNonOverlappingAndDenseIndicator to `_sympy.functions.py`
- Moves SymNode to `fx.experimental.sym_node`.
- This file does not have any SymPy dependencies at import time
- It installs the magic methods in Sym{Bool,Int,Float}.
- N.b. With this split, we may be able to move Sym{Bool,Int,Float} to this file, and remove quite a few of the hacks around these classes
- Imports `sym_node` in `torch/__init__.py` rather than the whole `symbolic_shapes.py`.
This breaks the import-time dependency between torch and SymPy
