it's a bit counterintuitive that the exceptions are the named cases

Should empty_lines be inlined into empty_lines_before_trailing_comments. It seems the function is only used in stmt_function_def and stmt_class_def and both use the same implementation.

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 (psf/black#3861). Additionally, it assumes the style proposed in psf/black#3862.
An edge case that also surfaced with typeshed are newline before trailing module comments.

Closes #6723
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.
