Lint `Tools/build` using existing ruff configuration

[picnixz]

Feature or enhancement

Proposal:

There is an existing Tools/build/.ruff.toml that is for now only used by the check-warnings.py script. I've tried to minimize the number of changes but I ran ruff check Tools/build and selectively disabled some existing errors so that in the future we can selectively fix them.

Note that @hugovk recently ruffed the tools in #124382 but not all of them.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

@encukou I've just seen your disapproval on this one. I eventually only changed some lines either for readability or because there were usage of deprecated features (such as using typing.* instead of known generics). If you want some of your owned files to be removed from the list of ruffed ones, feel free to make a follow-up PR.

No one has "owned" files here.
But as the main author of stable_abi.py, I do dislike the arbitrary formatting decisions. I'd prefer avoiding style-only changes, and sticking to PEP 8 if they're really necessary.
Also, from my experience with Ruff in CI, the failure messages can be rather opaque.
