Summary:
This PR greatly simplifies `mypy-strict.ini` by strictly typing everything in `.github` and `tools`, rather than picking and choosing only specific files in those two dirs. It also removes `warn_unused_ignores` from `mypy-strict.ini`, for reasons described in https://github.com/pytorch/pytorch/pull/56402#issuecomment-822743795: basically, that setting makes life more difficult depending on what libraries you have installed locally vs in CI (e.g. `ruamel`).

Summary:
[distutils](https://docs.python.org/3/library/distutils.html) is on its way out and will be deprecated-on-import for Python 3.10+ and removed in Python 3.12 (see [PEP 632](https://www.python.org/dev/peps/pep-0632/)). There's no reason for us to keep it around since all the functionality we want from it can be found in `setuptools` / `sysconfig`. `setuptools` includes a copy of most of `distutils` (which is fine to use according to the PEP), that it uses under the hood, so this PR also uses that in some places.

Summary:
We are trying to build libtorch statically (BUILD_SHARED_LIBS=OFF) then link it into a DLL. Our setup hits the infinite loop mentioned [here](54c05fa34e/torch/csrc/autograd/engine.cpp (L228)) because we build with `BUILD_SHARED_LIBS=OFF` but still link it all into a DLL at the end of the day.
This PR fixes the issue by changing the condition to guard on which windows runtime the build links against using the `CAFFE2_USE_MSVC_STATIC_RUNTIME` flag. `CAFFE2_USE_MSVC_STATIC_RUNTIME` defaults to ON when `BUILD_SHARED_LIBS=OFF`, so backwards compatibility is maintained.
I'm not entirely confident I understand the subtleties of the windows runtime versus linking setup, but this setup works for us and should not affect the existing builds.

Summary:
## Motivation
This PR upgrades MKL-DNN from v0.20 to DNNL v1.2 and resolves https://github.com/pytorch/pytorch/issues/30300.
DNNL (Deep Neural Network Library) is the new brand of MKL-DNN, which improves performance, quality, and usability over the old version.
This PR focuses on the migration of all existing functionalities, including minor fixes, performance improvement and code clean up. It serves as the cornerstone of our future efforts to accommodate new features like OpenCL support, BF16 training, INT8 inference, etc. and to let the Pytorch community derive more benefits from the Intel Architecture.
<br>
## What's included?
Even DNNL has many breaking changes to the API, we managed to absorb most of them in ideep. This PR contains minimalist changes to the integration code in pytorch. Below is a summary of the changes:
<br>
**General:**
1. Replace op-level allocator with global-registered allocator
```
// before
ideep::sum::compute<AllocForMKLDNN>(scales, {x, y}, z);
// after
ideep::sum::compute(scales, {x, y}, z);
```
The allocator is now being registeted at `aten/src/ATen/native/mkldnn/IDeepRegistration.cpp`. Thereafter all tensors derived from the `cpu_engine` (by default) will use the c10 allocator.
```
RegisterEngineAllocator cpu_alloc(
ideep::engine::cpu_engine(),
[](size_t size) {
return c10::GetAllocator(c10::DeviceType::CPU)->raw_allocate(size);
},
[](void* p) {
c10::GetAllocator(c10::DeviceType::CPU)->raw_deallocate(p);
}
);
```
------
2. Simplify group convolution
We had such a scenario in convolution where ideep tensor shape mismatched aten tensor: when `groups > 1`, DNNL expects weights tensors to be 5-d with an extra group dimension, e.g. `goihw` instead of `oihw` in 2d conv case.
As shown below, a lot of extra checks came with this difference in shape before. Now we've completely hidden this difference in ideep and all tensors are going to align with pytorch's definition. So we could safely remove these checks from both aten and c2 integration code.
```
// aten/src/ATen/native/mkldnn/Conv.cpp
if (w.ndims() == x.ndims() + 1) {
AT_ASSERTM(
groups > 1,
"Only group _mkldnn_conv2d weights could have been reordered to 5d");
kernel_size[0] = w.get_dim(0) * w.get_dim(1);
std::copy_n(
w.get_dims().cbegin() + 2, x.ndims() - 1, kernel_size.begin() + 1);
} else {
std::copy_n(w.get_dims().cbegin(), x.ndims(), kernel_size.begin());
}
```
------
3. Enable DNNL built-in cache
Previously, we stored DNNL jitted kernels along with intermediate buffers inside ideep using an LRU cache. Now we are switching to the newly added DNNL built-in cache, and **no longer** caching buffers in order to reduce memory footprint.
This change will be mainly reflected in lower memory usage from memory profiling results. On the code side, we removed couple of lines of `op_key_` that depended on the ideep cache before.
------
4. Use 64-bit integer to denote dimensions
We changed the type of `ideep::dims` from `vector<int32_t>` to `vector<int64_t>`. This renders ideep dims no longer compatible with 32-bit dims used by caffe2. So we use something like `{stride_.begin(), stride_.end()}` to cast parameter `stride_` into a int64 vector.
<br>
**Misc changes in each commit:**
**Commit:** change build options
Some build options were slightly changed, mainly to avoid name collisions with other projects that include DNNL as a subproject. In addition, DNNL built-in cache is enabled by option `DNNL_ENABLE_PRIMITIVE_CACHE`.

† Shufflenet is one of the few models that require temp buffers during inference. The performance degradation is an expected issue since we no longer cache any buffer in the ideep. As for the solution, we suggest users opt for caching allocator like **jemalloc** as a drop-in replacement for system allocator in such heavy workloads.

Summary:
## Several flags
`/MP[M]`: It is a flag for the compiler `cl`. It leads to object-level multiprocessing. By default, it spawns M processes where M is the number of cores on the PC.
`/maxcpucount:[M]`: It is a flag for the generator `msbuild`. It leads to project-level multiprocessing. By default, it spawns M processes where M is the number of cores on the PC.
`/p:CL_MPCount=[M]`: It is a flag for the generator `msbuild`. It leads the generator to pass `/MP[M]` to the compiler.
`/j[M]`: It is a flag for the generator `ninja`. It leads to object-level multiprocessing. By default, it spawns M processes where M is the number of cores on the PC.
## Reason for the change
1. Object-level multiprocessing is preferred over project-level multiprocessing.
2. ~For ninja, we don't need to set `/MP` otherwise M * M processes will be spawned.~ Actually, it is not correct because in ninja configs, there are only one source file in the command. Therefore, the `/MP` switch should be useless.
3. For msbuild, if it is called through Python configuration scripts, then `/p:CL_MPCount=[M]` will be added, otherwise, we add `/MP` to `CMAKE_CXX_FLAGS`.
4. ~It may be a possible fix for https://github.com/pytorch/pytorch/issues/28271, https://github.com/pytorch/pytorch/issues/27463 and https://github.com/pytorch/pytorch/issues/25393. Because `/MP` is also passed to `nvcc`.~ It is probably not true. Because `/MP` should not be effective given there is only one source file per command.

What dist_check.py does is largely merely determining whether we should

will always be overrided by gloo:
2101e02cea/cmake/Dependencies.cmake (L19-L28)
Since dist_check.py becomes irrelevant, this commit also simplifies the
setting of `USE_DISTRIBUTED` (by removing its explicit setting in Python scripts), and deprecate `USE_GLOO_IBVERBS` in favor
of `USE_IBVERBS`.

Summary:
---
How does the current code subsume all detections in the deleted `nccl.py`?
- The dependency of `USE_NCCL` on the OS and `USE_CUDA` is handled as dependency options in `CMakeLists.txt`.
- The main NCCL detection happens in [FindNCCL.cmake](8377d4b32c/cmake/Modules/FindNCCL.cmake), which is called by [nccl.cmake](8377d4b32c/cmake/External/nccl.cmake). When `USE_SYSTEM_NCCL` is false, the previous Python code defer the detection to `find_package(NCCL)`. The change in `nccl.cmake` retains this.
- `USE_STATIC_NCCL` in the previous Python code simply changes the name of the detected library. This is done in `IF (USE_STATIC_NCCL)`.
- Now we only need to look at how the lines below line 20 in `nccl.cmake` are subsumed. These lines list paths to header and library directories that NCCL headers and libraries may reside in and try to search these directories for the key header and library files in turn. These are done by `find_path` for headers and `find_library` for the library files in `FindNCCL.cmake`.
* The call of [find_path](https://cmake.org/cmake/help/v3.8/command/find_path.html) (Search for `NO_DEFAULT_PATH` in the link) by default searches for headers in `<prefix>/include` for each `<prefix>` in `CMAKE_PREFIX_PATH` and `CMAKE_SYSTEM_PREFIX_PATH`. Like the Python code, this commit sets `CMAKE_PREFIX_PATH` to search for `<prefix>` in `NCCL_ROOT_DIR` and home to CUDA. `CMAKE_SYSTEM_PREFIX_PATH` includes the standard directories such as `/usr/local` and `/usr`. `NCCL_INCLUDE_DIR` is also specifically handled.
* Similarly, the call of [find_library](https://cmake.org/cmake/help/v3.8/command/find_library.html) (Search for `NO_DEFAULT_PATH` in the link) by default searches for libraries in directories including `<prefix>/lib` for each `<prefix>` in `CMAKE_PREFIX_PATH` and `CMAKE_SYSTEM_PREFIX_PATH`. But it also handles the edge cases intended to be solved in the Python code more properly:
- It only searches for `<prefix>/lib64` (and `<prefix>/lib32`) if it is appropriate on the system.
- It only searches for `<prefix>/lib/<arch>` for the right `<arch>`, unlike the Python code searches for `lib/<arch>` in a generic way (e.g., the Python code searches for `/usr/lib/x86_64-linux-gnu` but in reality systems have `/usr/lib/x86_64-some-customized-name-linux-gnu`, see https://unix.stackexchange.com/a/226180/38242 ).
---
Regarding for relevant issues:
- https://github.com/pytorch/pytorch/issues/12063 and https://github.com/pytorch/pytorch/issues/2877: These are properly handled, as explained in the updated comment.
- https://github.com/pytorch/pytorch/issues/2941 does not changes NCCL detection specifically for Windows (it changed CUDA detection).
- b7e258f81e A versioned library detection is added, but the order is reversed: The unversioned library becomes preferred. This is because normally unversioned libraries are linked to versioned libraries and preferred by users, and local installation by users are often unversioned. Like the document of [find_library](https://cmake.org/cmake/help/v3.8/command/find_library.html) suggests:
> When using this to specify names with and without a version suffix, we recommend specifying the unversioned name first so that locally-built packages can be found before those provided by distributions.

This is a preliminary change outlining the approach we plan to follow to integrate QNNPACK operators into the pytorch backend. The operators will not be made visible to the user in the python world, so ultimately we will have a function that calls qnnpack backend based on the environment being run on.
The goal of the project is to integrate QNNPACK library with PyTorch to achieve good performance for quantized mobile models.

Summary:
ROCm is already detected in cmake/public/LoadHIP.cmake. No need to
detect twice. Plus, the Python script read environment variable
ROCM_HOME, but what is really used in CMake scripts is ROCM_PATH -- A
user must specify both environment variables right. Since ROCM_HOME is
undocumented, this commit completely eradicates it.

Summary:
Currently the build system accepts USE_NAMEDTENSOR from the environment
variable and turns it into NAMEDTENSOR_ENABLED when passing to CMake.
This discrepancy does not seem necessary and complicates the build
system. The naming of this build option is also semantically incorrect
("BUILD_" vis-a-vis "USE_"). This commit eradicate this issue before it
is made into a stable release.
The support of NO_NAMEDTENSOR is also removed, since PyTorch has been
quite inconsistent about "NO_*" build options.
---
Note: All environment variables with their names starting with `BUILD_` are currently automatically passed to CMake with no need of an additional wrapper.

Summary:
`setup.py` recommends setting `USE_QNNPACK=0` and `USE_NNPACK=0` to disable building QNNPACK and NNPACK respectively. However this wasn't reflected correctly because we were looking for `NO_QNNPACK` and `NO_NNPACK`. This PR fixes it.

Summary:
This is yet another step to disentangle Python build scripts and CMake
and improve their integration (Let CMake handle more build environment
detections, and less by our handcrafted Python scripts).
The processor detection logic also changed a bit: Instead of detecting
whether the system processor is PPC or ARM, this PR changes to detect
Intel CPUs, because this is more precise as MKL only supports Intel
CPUs. The build option `USE_MKLDNN` will also not be presented to
users on non-Intel processors.

Summary:
Currently many build options are explicitly passed from Python build scripts to CMake. But this is unecessary, at least for many of them. This commit removes the build options that have the same name in CMakeLists.txt and environment variables (e.g., `USE_REDIS`). Additionally, many build options that are not explicitly passed to CMake are lost.
For `ONNX_ML`, `ONNX_NAMESPACE`, and `BUILDING_WITH_TORCH_LIBS`, I changed their default values in CMake scripts (as consistent with what the `CMake.defines` call meant), to avoid their default values being redundantly set in the Python build scripts.

Summary:
Currently when building extensions, variables such as USE_CUDA, USE_CUDNN are used to determine what libraries should be linked. But we should use what CMake has detected, because:
1. If CMake found them unavailable but the variables say some libraries should be linked, the build would fail.
2. If the first build is made using a set of non-default build options, rebuild must have these option passed to setup.py again, otherwise the extension build process is inconsistent with CMake. For example,
```bash
# First build
USE_CUDA=0 python setup.py install
# Subsequent builds like this would fail, unless "build/" is deleted
python setup.py install
```
This commit addresses the above issues by using variables from CMakeCache.txt when building the extensions.
---
The changes in `setup.py` may look lengthy, but the biggest changed block is mostly moving them into a function `configure_extension_build` (along with some variable names changed to `cmake_cache_vars['variable name']` and other minor changes), because it must be called after CMake has been called (and thus the options used and system environment detected by CMake become available).
