Switch to `uv pip compile`

[CoolCat467]

This pull request follows up on #2956 and is attempting to switch the continuous integration system to use astral.sh' new tool uv. This particular pull request is a subset of #2957 and is in charge of only replacing pip-compile.

This seems nontrivial, can we break this into 2 prs?

1. replace pip-compile

2. replace pip install

Personally I see (1) as much more valuable-- (2) doesn't change much. Personally I'm more excited by uv's ability to get the lowest compatible version so we can add a new CI run than by it replacing pip install.

uv seems to support keeping keeping things like implementation_name now: https://github.com/astral-sh/uv/pull/4503

I think once this uses that flag, this is good for me

[CoolCat467]

So, added --no-strip-markers, but since there hasn't been a proper release with these changes yet, using a git commit dependency for uv at the moment, which works, but CI fails because full cargo isn't installed on the windows or alpine runners.

I think we just need to wait for a proper release with these changes to come out, but otherwise this pull request should be almost done!

Heads up we plan to cut a release today.

Ok so it looks like everything is working except for an issue that happens when importing cryptography on the 3.13 runner, with this error: E ImportError: /opt/hostedtoolcache/Python/3.13.0-beta.2/x64/lib/python3.13/site-packages/_cffi_backend.cpython-313-x86_64-linux-gnu.so: undefined symbol: _PyErr_WriteUnraisableMsg

I don't think this is caused by uv, probably an issue with cryptography. Version that 3.13 runner used to have this result: cryptography-42.0.8

[A5rocks]

I'm surprised pulling in master didn't work. I manually edited the test requirements to use a pre-release of cffi (IIRC? Or maybe cryptography) to fix that.

Pretty sure it isn't related to this pull request's changes though, going to try to get CI to run again. Might be an instance of test flakiness.
