move version_h to shared build structure in Buck (#75964)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/75964
This is already in the shared build structure for Bazel, but we need
to implement genrule for fbcode.
There's an xplat target that can't build in fbcode yet because the
dependencies don't line up, so we have to add a tag to exclude it.
