merge some of the lint checks (#28933)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/28933
Merge all the things that don't add annotations into a single
`quick-checks` job. This helps reduce concurrency and clutter
at the top of the status check page.
This doesn't touch the actually important items (flake8 + clang-tidy),
but those are a little trickier to handle because of how annotations are
added.
