Sort lazy import statements

[DanielNoord]

Asked Copilot to create a first attempt at #2462

It will require some polishing, especially in the tests. However, the approach seems sensible to me. @staticdev what do you think of this direction?

@copilot Fix review

[DanielNoord]

Only DeepSource fails, but that is a stupid test anyway...

@staticdev Do you have some time to review this? I think it is actually in quite a good state now.

My plan is to merge this and release a beta version of isort. I will announce this on the original PEP thread in Discourse (and other channels if I find them) to see if users have initial feedback.
After a while we can then release an actual version. Probably somewhat after the first beta of Python 3.15.

@DanielNoord I started reading the peps to better understand how the lazy imports will work. I will put a bit more effort to keep up and it is very cool you were already able to do some testing. This one is a big one, congratulations already for your efforts.

I will do my best to start with the code ASAP.

I think for now we should just mimic the behaviour of ruff, nobody benefits from us and them having different standards for the sorting.

The PEP doesn't say anything about preferred sorting order, but the order ruff implemented makes a lot of sense to me.

Gooiemorgen,
Do you have a link of how they implemented?

See astral-sh/ruff#21305 :)

I also took their example and used it as a test case in our code!
