Slim down pytorch-cuda

It should only contain runtime dependencies that PyTorch+domain
libraries depend on, namely:
 - cudart
 - cublas
 - cusparse
 - cufft
 - curand
 - nvtx
 - nvrtc
 - nvjpeg (for TorchVision)

This removes dependencies on NVCC, build/debug tools, etc which are not
needed for running the pytorch

Test Plan:
  `conda create -n tmp -c nvidia -c malfet cuda-toolkit==11.7` and
observe that only relevant packages are installed

Fixes pytorch/pytorch#91334
