Avoid reusing cached downloaded binaries with `--no-binary` (#7772)
## Summary
Historically, we've allowed the use of wheels that were downloaded from
PyPI even when the user passes `--no-binary`, if the wheel exists in the
cache. This PR modifies the cache lookup code such that we respect
`--no-build` and `--no-binary` in those paths.
Closes https://github.com/astral-sh/uv/issues/2154.
