Make --reinstall imply --refresh (#5425)

## Summary

It's hard for me to imagine a scenario in which a user passed
`--reinstall`, but wanted us to keep respecting cached data for a
package. For example, to actually "rebuild and reinstall" an editable
today, you have to pass both `--reinstall` and `--refresh`.

This PR makes `--reinstall` imply `--refresh`, so we always validate
that the cached data is fresh.

Closes https://github.com/astral-sh/uv/issues/5424.
