fix nvrtc PTX architecture cap for CUDA toolkit (#48455)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/48200
CUDA 11.0 only supports < sm_80 (https://docs.nvidia.com/cuda/archive/11.0/nvrtc/#group__options)
Note: NVRTC documentation is not a reliable source to query supported architecture. Rule of thumb is that nvrtc supports the same set of arch for nvcc, so the best way to query that is something like `nvcc -h | grep -o "compute_[0-9][0-9]" | sort | uniq`
