Lock dependency groups in the uv pip interface, i.e., uv pip compile --group

[KasperZutterman]

Hi all,

Similar to #8590 it would be great if the PEP 735 dependency-groups could be locked with uv pip compile.

I would imagine something like: uv pip compile pyproject.toml -o requirements-dev.txt --group=test.

Linking this for possible interface alignment:

• Eventually implement support for the PEP 735 "dependency groups" jazzband/pip-tools#2062

👍 We'll do this, likely as soon as the interface is defined for pip itself.
