Add uv python install --default (#8650)

Adds a `--default` flag to `uv python install` in preview. This includes
a `python` and `python{major}` executable in addition to the
`python{major}.{minor}` executable. We will replace uv-managed
executables, but externally managed executables require the `--force`
flag to overwrite.

If you run `uv python install` (without arguments), we include the
`--default` flag implicitly to populate `python` and `python3` for the
"default" install version.

In the future, we should add a warning if the installed executable isn't
at the front of the PATH.
