[bazel] enable sccache+nvcc in CI (#95528)
Fixes #79348
This change is mostly focused on enabling nvcc+sccache in the PyTorch CI.
Along the way we had to do couple tweaks:
1. Split the rules_cc from the rules_cuda that embeeded them before. This is needed in order to apply a different patch to the rules_cc compare to the one that rules_cuda does by default. This is in turn needed because we need to workaround an nvcc behavior where it doesn't send `-iquote xxx` to the host compiler, but it does send `-isystem xxx`. So we workaround this problem with (ab)using `-isystem` instead. Without it we are getting errors like `xxx` is not found.
2. Workaround bug in bazel https://github.com/bazelbuild/bazel/issues/10167 that prevents us from using a straightforward and honest `nvcc` sccache wrapper. Instead we generate ad-hock bazel specific nvcc wrapper that has internal knowledge of the relative bazel paths to local_cuda. This allows us to workaround the issue with CUDA symlinks. Without it we are getting `undeclared inclusion(s) in rule` all over the place for CUDA headers.
## Test plan
