I.e. when `MTL_CAPTURE_ENABLED` environment variable is set to 1, one should be able to invoke wrap the code with `torch.mps.profiler.capture_metal` to generate gputrace for shaders invoked inside the context manager.
For example, code below:
```python
import torch
import os
def foo(x):
return x[:,::2].sin() + x[:, 1::2].cos()
if __name__ == "__main__":
os.environ["MTL_CAPTURE_ENABLED"] = "1"
x = torch.rand(32, 1024, device="mps")
with torch.mps.profiler.metal_capture("compiled_shader"):
torch.compile(foo)(x)
```
should capture the execution of a `torch.compile` generated shader

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

Prerequisite for adding more complex type support and FFT operation
Check using `conjugateWithTensor:name:` selector defined as follows
```objc
/// Returns the complex conjugate of the input tensor elements.
///
/// - Parameters:
/// - tensor: The input tensor.
/// - name: An optional string which serves as an identifier for the operation..
/// - Returns: A valid `MPSGraphTensor` object containing the elementwise result of the applied operation.
-(MPSGraphTensor *) conjugateWithTensor:(MPSGraphTensor *) tensor
name:(NSString * _Nullable) name
MPS_AVAILABLE_STARTING(macos(14.0), ios(17.0), tvos(17.0))
MPS_SWIFT_NAME( conjugate(tensor:name:) );

- Rename `isOnMacOS13orNewer(unsigned minor)` hook to `isOnMacOSorNewer(major, minor)`
- Replace `torch._C.__mps_is_on_macos_13_or_newer` with `torch._C._mps_is_on_macos_or_newer`
- Add `torch.backends.mps.is_macos_or_newer` public API

- Implement `MPSEventPool` to recycle events.
- Implement python bindings with `torch.mps.Event` class using the MPSEventPool backend. The current member functions of the Event class are `record()`, `wait()`, `synchronize()`, `query()`, and `elapsed_time()`.
- Add API to measure elapsed time between two event recordings.
- Added documentation for Event class to `mps.rst`.
- Added test case to `test_mps.py`.

Will be needed if one wants to make accurate XFAIL validation
I.e. `torch.backends.mps.is_macos13_or_newer()` will return True if PyTorch is running on MacOS 13.0 or newer, `torch.backends.mps.is_macos13_or_newer(1)` will return True if running on MacOS 13.1 or newer and `torch.backends.mps.is_macos13_or_newer(2)` will return True if running on MacOS 13.2 or newer
Do not use 13.3 check as `@available` does not really work for shared libraries

- To check for Memory Leaks in `test_mps.py`, set the env-variable `PYTORCH_TEST_MPS_MEM_LEAK_CHECK=1` when running test_mps.py (used CUDA code as reference).
- Added support for the following new python interfaces in MPS module:
`torch.mps.[empty_cache(), set_per_process_memory_fraction(), current_allocated_memory(), driver_allocated_memory()]`
- Renamed `_is_mps_on_macos_13_or_newer()` to `_mps_is_on_macos_13_or_newer()`, and `_is_mps_available()` to `_mps_is_available()` to be consistent in naming with prefix `_mps`.

- This PR is a prerequisite for the upcoming Memory Leak Detection PR.
- Enable global manual seeding via `torch.manual_seed()` + test case
- Add `torch.mps.synchronize()` to wait for MPS stream to finish + test case
- Enable the following python interfaces for MPS:
`torch.mps.[get_rng_state(), set_rng_state(), synchronize(), manual_seed(), seed()]`
- Added some test cases in test_mps.py
- Added `mps.rst` to document the `torch.mps` module.
- Fixed the failure with `test_public_bindings.py`
Description of new files added:
- `torch/csrc/mps/Module.cpp`: implements `torch._C` module functions for `torch.mps` and `torch.backends.mps`.
- `torch/mps/__init__.py`: implements Python bindings for `torch.mps` module.
