Automatic updates from Ruff for Python 3.9+

[abravalheri]

Summary of changes

Implement @Avasam suggestions from #4718 (comment):

• functools.lru_cache(maxsize=None) can be replaced by functools.cache
• Callable, Generator, Iterator, Iterable, Sequence, Mapping, MutableMapping should be imported from collections.abc instead of typing
• Type, Dict, List, Tuple should be replaced by their builtin variant

The procedure used for the changes is:

1. Modify ruff.toml as suggested in Remove unnecessary code paths for 3.9+ (follow up on skeleton changes) #4718 (comment)
2. Run ruff check --fix --unsafe-fixes
3. Manually add the missing fixes
4. Manually check all files and add improvements as necessary
5. git restore ruff.toml (I am leaving this decision for skeleton for the time being)
6. git restore setuptools/_importlib.py (Already covered in Remove unnecessary code paths for 3.9+ (follow up on skeleton changes) #4718)

Idk if we want the F841 preview of removing/marking unused variables ?
As in, it's not a 3.8 -> 3.9 change, but rather caused by setuptool's Ruff configs not using preview behaviour by default for the linter (preview is enabled for the formatter).

You are right. I should, at least, separate it into to 2 PRs. I will have a look at it later, thank you.

Removed the changes for F841

This thing of pypy jobs randomly being cancelled by GHA is becoming inconvenient.

I was surprised that Ruff didn't also move Callable. Apparently there's runtime issues with Callable and generic params in 3.9.0 and 3.9.1.

I'll assume setuptools aims at supporting all patch versions if possible. If so, Ruff is right and no manual change needed ! (at least when not used in an annotation with from __future__ import annotations)

[abravalheri]

Perfect, thank you very much @Avasam, for the thorough review.

I think from this set of PRs, the only controversial one is the one I remove the vendored copy of importlib_resources, so I am waiting a little bit before merging that one.

But we should be able to merge this PR with relatively ease.

The typing looks fine and is 3.9 compatible 👍🏻
