Port all git functionality to use git CLI (#3833)

## Summary

We currently rely on libgit2 for most git-related functionality.
However, libgit2 has long-standing performance issues, as well as lags
significantly behind git in terms of new features. For these reasons we
now use the git CLI by default for fetching repositories
(https://github.com/astral-sh/uv/pull/1781). This PR completely drops
libgit2 in favor of the git CLI for all git-related functionality, which
should allow us to use features such as partial clones and sparse
checkouts in the future for performance.

There is also a lot of technical debt in the current git code as it's
mostly taken from Cargo. Switching to the git CLI *vastly* simplifies
the `uv-git` codebase.

Eventually we might want to look into switching to
[`gitoxide`](https://github.com/Byron/gitoxide), but it's currently too
immature for our use case.
