Add additional conditions to `build_pytorch_libs.py` to avoid fetching NCCL when `USE_CUDA` or `USE_NCCL` are disabled. While at it, adjust the existing condition for `USE_SYSTEM_NCCL` to use the utility function.

Newer versions of distutils no longer import `_msvccompiler` upon init(on Windows platform, that was not the case on other platforms even before 74), but it's still accessible if one chooses to import it directly.
Test plan:
```
% python -c 'from setuptools import distutils; print(distutils.__version__, hasattr(distutils, "_msvccompiler")); from distutils import _msvccompiler; import setuptools; print(setuptools.__version__, _msvccompiler.__file__)'
3.10.9 False
65.5.0 /usr/local/fbcode/platform010/Python3.10.framework/Versions/3.10/lib/python3.10/site-packages/setuptools/_distutils/_msvccompiler.py
```
and
```
% python -c 'from setuptools import distutils; print(distutils.__version__, hasattr(distutils, "_msvccompiler")); from distutils import _msvccompiler; import setuptools; print(setuptools.__version__, _msvccompiler.__file__)'
3.13.0 False
75.6.0 /Users/malfet/py312-venv/lib/python3.13/site-packages/setuptools/_distutils/_msvccompiler.py
```
Gave up trying to appease the linker, so rewrote it as following function:
```python
def _get_vc_env(vc_arch: str) -> dict[str, str]:
try:
from setuptools import distutils # type: ignore[import]
return distutils._msvccompiler._get_vc_env(vc_arch) # type: ignore[no-any-return]
except AttributeError:
from setuptools._distutils import _msvccompiler #type: ignore[import]
return _msvccompiler._get_vc_env(vc_arch) # type: ignore[no-any-return]
```
This PR also undoes setuptools version restriction introduced by https://github.com/pytorch/pytorch/pull/136489 as premise for restriction is incorrect

With ufmt in place https://github.com/pytorch/pytorch/pull/81157, we can now use it to gradually format all files. I'm breaking this down into multiple smaller batches to avoid too many merge conflicts later on.
This batch (as copied from the current BLACK linter config):
* `tools/**/*.py`
Upcoming batchs:
* `torchgen/**/*.py`
* `torch/package/**/*.py`
* `torch/onnx/**/*.py`
* `torch/_refs/**/*.py`
* `torch/_prims/**/*.py`
* `torch/_meta_registrations.py`
* `torch/_decomp/**/*.py`
* `test/onnx/**/*.py`
Once they are all formatted, BLACK linter will be removed.

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.

FindCUDA.cmake. Search for nvcc in path has been added to FindCUDA.cmake (https://github.com/pytorch/pytorch/issues/29160). The Windows default path part is moved to
build_pytorch_libs.py. CUDA_HOME is kept for now because other parts of
the build system is still using it.

FindCUDNN.cmake and cuda.cmake have done the detection. This commit deletes `tools/setup_helpers/cudnn.py` as it is no longer needed.
Previously in https://github.com/pytorch/pytorch/issues/25482, one test failed because TensorRT detects cuDNN differently, and there may be situations we can find cuDNN but TensorRT cannot. This is fixed by passing our detection result down to TensorRT.

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).

Summary:
Instead of attempting to hardcode calls to "ninja" or "make", we should always let cmake do it. This better integrates build configurations (DEBUG or REL_WITH_DEB_INFO) and better handles the case in which the native build tool is not in PATH (cmake has some capacity to find them and has options for users to specify their locations).

First time this was merged it broke master and was reverted. This time I do not add ```set -u``` to the .circleci/scripts/setup* scripts. There's still a chance that ```set -u``` breaks the binary builds on master, but at least those can be fixed in parallel and don't completely eliminate signal from all merges.

Summary:
This PR is an intermediate step toward the ultimate goal of eliminating "caffe2" in favor of "torch". This PR moves all of the files that had constituted "libtorch.so" into the "libcaffe2.so" library, and wraps "libcaffe2.so" with a shell library named "libtorch.so". This means that, for now, `caffe2/CMakeLists.txt` becomes a lot bigger, and `torch/CMakeLists.txt` becomes smaller.
The torch Python bindings (`torch_python.so`) still remain in `torch/CMakeLists.txt`.
The follow-up to this PR will rename references to `caffe2` to `torch`, and flatten the shell into one library.
