## Summary
Fix all but one empty line differences with the black preview style in
typeshed. The remaining differences are breaking with type comments and
trailing commas in function definitions.
I compared the empty line differences with the preview mode of black
since stable has some oddities that would have been hard to replicate
(https://github.com/psf/black/issues/3861). Additionally, it assumes the
style proposed in https://github.com/psf/black/issues/3862.
An edge case that also surfaced with typeshed are newline before
trailing module comments.

## Test Plan
The main driver was the typeshed diff. I added new test cases for all
kinds of possible empty line combinations in stub files, test cases for
newlines before trailing module comments.
