Pull upstream select_compute_arch from cmake for Ampere (#41133)
Summary:
This pulls the following merge requests from CMake upstream:
- https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4979
- https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4991
The above two merge requests improve the Ampere build:
- If `TORCH_CUDA_ARCH_LIST` is not set, it can now automatically pickup 8.0 as its part of its default value
- If `TORCH_CUDA_ARCH_LIST=Ampere`, it no longer fails with `Unknown CUDA Architecture Name Ampere in CUDA_SELECT_NVCC_ARCH_FLAGS`
Codes related to architecture < 3.5 are manually removed because PyTorch no longer supports it.
