This PR adds a linker script optimization based on prioritized symbols that can be extracted from the profiles of popular workloads. The present linker script was generated to target ARM+CUDA and later can be extended if necessary. The reason we target ARM is shown below:
> PyTorch and other applications that access more than 24x 2MB code regions in quick succession can result in performance bottlenecks in the CPU front-end. The link-time optimization improves executable code locality and improve performance. We recommend turning on the optimization always for PyTorch and other application that behaves similarly.

Summary: The current C shim layer manually implements a C interface for a handful of ops. Obviously that's not scalable if we want to extend it to cover all aten ops. This new torchgen script automatically generates C shim interfaces for CPU and CUDA backends. The interface follows the same parameter passing rules as the current C shim layer, such as
* Use plain C data types to pass parameters
* Use AtenTensorHandle to pass at::Tensor
* Use pointer type to pass optional parameter
* Use pointer+length to pass list
* Use device_type+device_index to pass device
* When a parameter is a pointer of pointer, e.g. AtenTensorHandle**, the script generates either a list of optional values or an optional list of values
https://gist.github.com/desertfire/83701532b126c6d34dae6ba68a1b074a is an example of the generated torch/csrc/inductor/aoti_torch/generated/c_shim_cuda.cpp file. The current version doesn't generate C shim wrappers for all aten ops, and probably generates more wrappers than needed on the other hand, but it should serve as a good basis.
This PR by itself won't change AOTI codegen and thus won't introduce any FC breakage. The actual wrapper codegen changes will come in another PR with some version control flag to avoid FC breakage.

Some operations, such as GEMMs, could be implemented using more than one library or more than one technique. For example, a GEMM could be implemented for CUDA or ROCm using either the blas or blasLt libraries. Further, ROCm's rocblas and hipblaslt libraries allow the user to query for all possible algorithms and then choose one. How does one know which implementation is the fastest and should be chosen? That's what TunableOp provides.
See the README.md for additional details.
TunableOp was ported from onnxruntime starting from commit 08dce54266. The content was significantly modified and reorganized for use within PyTorch. The files copied and their approximate new names or source content location within aten/src/ATen/cuda/tunable include the following:

Summary:
This diff implements a mechanism for safely update torch.export serialization schema, aka schema.py, which is the API surface having the strongest compatibility guarantee.
The diff is consist of 3 changes:
- Added a script to "build" or "materialize" schema.py into a platform neutral format (yaml), which serves as the committed form of the seialization schema.
- Added unittest to compare against schema.py and schema.yaml, so that it forces developers to execute the updater script when there is mismatch between two files.
- Added a checker inside the updater script, so that all the compatible change will result in a minor version bump, and all the incompatible changes will result in a major version bump.
torch.export's serialization BC/FC policy is (tentatively) documented here: https://docs.google.com/document/d/1EN7JrHbOPDhbpLDtiYG4_BPUs7PttpXlbZ27FuwKhxg/edit#heading=h.pup7ir8rqjhx , we will update the
As noted in the code doc, people should be able to run the following command to update schema properly from now on:
```
python scripts/export/update_schema.py --prefix <path_to_torch_development_diretory>
or
buck run caffe2:export_update_schema -- --prefix /data/users/$USER/fbsource/fbcode/caffe2/

Fix https://github.com/pytorch/pytorch/issues/97352.
This PR changes the way the linking to intel MKL is done and updating MKL on Windows to mkl-2021.4.0 .
There are for both conda and pip packages MKL version with which you can link dynamically. mkl-devel contains the static versions of the dlls and MKL contains the needed dlls for the runtime. MKL dlls and static libs starting with 2021.4.0 have the version in their names( for MKL 2023 we have mkl_core.2.dll and for 2021.4.0 we have mkl_core.1.dll) so its possible to have multiple versions installed and it will work properly.
For the wheel build, I added dependency for whell MKL and on conda a dependecy for the conda MKL and on libtorch I copied the MKL binaries in libtorch.
In order to test this PR I have to use custom builder https://github.com/pytorch/builder/pull/1467

# Motivation
As mentioned in [[RFC] Intel GPU Runtime Upstreaming](https://github.com/pytorch/pytorch/issues/114842), The first runtime component we would like to upstream is `Device` which contains the device management functions of Intel GPU's runtime. To facilitate the code review, we split the code changes into 4 PRs. This is one of the 4 PRs and covers the changes under `c10`.
# Design
Intel GPU device is a wrapper of sycl device on which kernels can be executed. In our design, we will maintain a sycl device pool containing all the GPU devices of the current machine, and manage the status of the device pool by PyTorch. The thread local safe is considered in this design. The corresponding C++ files related to `Device` will be placed in c10/xpu folder. And we provide the c10 device runtime APIs, like
- `c10::xpu::device_count`
- `c10::xpu::set_device`
- ...
# Additional Context
In our plan, 4 PRs should be submitted to PyTorch for `Device`:
1. for c10
2. for aten
3. for python frontend
4. for lazy initialization shared with CUDA

Related to #103973#110532#108404#94891
**Context:**
As commented in 6ae0554d11/cmake/Dependencies.cmake (L1198)
Kernel asserts are enabled by default for CUDA and disabled for ROCm.
However it is somewhat broken, and Kernel assert was still enabled for ROCm.
Disabling kernel assert is also needed for users who do not have PCIe atomics support. These community users have verified that disabling the kernel assert in PyTorch/ROCm platform fixed their pytorch workflow, like torch.sum script, stable-diffusion. (see the related issues)
**Changes:**
This pull request serves the following purposes:
* Refactor and clean up the logic, make it simpler for ROCm to enable and disable Kernel Asserts
* Fix the bug that Kernel Asserts for ROCm was not disabled by default.
Specifically,
- Renamed `TORCH_DISABLE_GPU_ASSERTS` to `C10_USE_ROCM_KERNEL_ASSERT` for the following reasons:
(1) This variable only applies to ROCm.
(2) The new name is more align with #define CUDA_KERNEL_ASSERT function.
(3) With USE_ in front of the name, we can easily control it with environment variable to turn on and off this feature during build (e.g. `USE_ROCM_KERNEL_ASSERT=1 python setup.py develop` will enable kernel assert for ROCm build).
- Get rid of the `ROCM_FORCE_ENABLE_GPU_ASSERTS' to simplify the logic and make it easier to understand and maintain
- Added `#cmakedefine` to carry over the CMake variable to C++
**Tests:**
(1) build with default mode and verify that USE_ROCM_KERNEL_ASSERT is OFF(0), and kernel assert is disabled:
```
python setup.py develop
```
Verify CMakeCache.txt has correct value.
```
/xxxx/pytorch/build$ grep USE_ROCM_KERNEL_ASSERT CMakeCache.txt
USE_ROCM_KERNEL_ASSERT:BOOL=0
```
Tested the following code in ROCm build and CUDA build, and expected the return code differently.
```
subprocess.call([sys.executable, '-c', "import torch;torch._assert_async(torch.tensor(0,device='cuda'));torch.cuda.synchronize()"])
```
This piece of code is adapted from below unit test to get around the limitation that this unit test now was skipped for ROCm. (We will check to enable this unit test in the future)
```
python test/test_cuda_expandable_segments.py -k test_fixed_cuda_assert_async
```
Ran the following script, expecting r ==0 since the CUDA_KERNEL_ASSERT is defined as nothing:
```
>> import sys
>>> import subprocess
>>> r=subprocess.call([sys.executable, '-c', "import torch;torch._assert_async(torch.tensor(0,device='cuda'));torch.cuda.synchronize()"])
>>> r
0
```
(2) Enable the kernel assert by building with USE_ROCM_KERNEL_ASSERT=1, or USE_ROCM_KERNEL_ASSERT=ON
```
USE_ROCM_KERNEL_ASSERT=1 python setup.py develop
```
Verify `USE_ROCM_KERNEL_ASSERT` is `1`
```
/xxxx/pytorch/build$ grep USE_ROCM_KERNEL_ASSERT CMakeCache.txt
USE_ROCM_KERNEL_ASSERT:BOOL=1
```
Run the assert test, and expected return code not equal to 0.
```
>> import sys
>>> import subprocess
>>> r=subprocess.call([sys.executable, '-c', "import torch;torch._assert_async(torch.tensor(0,device='cuda'));torch.cuda.synchronize()"])
>>>/xxxx/pytorch/aten/src/ATen/native/hip/TensorCompare.hip:108: _assert_async_cuda_kernel: Device-side assertion `input[0] != 0' failed.

Fixes#113940. This vendors the relevant parts of [`packaging==23.2.0`]() to have access to `Version` and `InvalidVersion` without taking a runtime dependency on `setuptools` or `packaging`.
I didn't find any vendoring policy so I put it under `torch._vendor.packaging`. While I have only vendored the files we need, I have not touched or trimmed the files otherwise.

Building with `USE_CUSTOM_DEBINFO=torch/csrc/Module.cpp python setup.py develop` for example will provide debug info only for this file.
This allows to enable debug symbols very fast from a non-debug build by doing a clean then develop (as long as you have ccache) and avoid very large binaries that take a very long time to load in gdb.
