## Summary

Add support for `@staticmethod`s. Overall, the changes are very similar
to #16305.

#18587 will be dependent on this PR for a potential fix of
astral-sh/ty#207.

mypy_primer will look bad since the new code allows ty to check more
code.

## Test Plan

Added new markdown tests. Please comment if there's any missing tests
that I should add in, thank you.
