Add typing to more build tools

[sobolevn]

Feature or enhancement

Right now we support typing in several build tools:

cpython/Tools/build/mypy.ini

Lines 2 to 4 in 6ce60f1

	files =
	Tools/build/compute-changes.py,
	Tools/build/generate_sbom.py

I think that some other files / tools from this folder can benefit from being checked with mypy.

I have a PR ready for Tools/build/update_file.py of parser.c generation.
What else can be easily typed?

Tools/build/verify_ensurepip_wheels.py also has annotations, but it is not checked. Will add in a separate PR, since it requires a bit of modification:

We should also merge #133405 before any other PR.

[Flosckow]

Can I work on it?

[sobolevn]

@Flosckow sure, you can help with #133403 (comment) I haven't started yet :)

Thank you!

[Flosckow]

@Flosckowконечно, вы можете помочь с #133403 (комментарий) Я еще не начал :)

Спасибо!

Yes, I'll try to do this, the only thing I might be a little slow is this is my first pr in cpython.

[sobolevn]

No worries, I can surely help with any questions you might have. Feel free to ask them :)
