Respect data scripts in uv tool install (#4693)

## Summary

Packages that provide scripts that _aren't_ Python entrypoints need to
respected in `uv tool install`. For example, Ruff ships a script in
`ruff-0.5.0.data/scripts`.

Unfortunately, the `.data` directory doesn't exist in the virtual
environment at all (it's removed, per the spec, after install). So this
PR changes the entry point detection to look at the `RECORD` file, which
is the only evidence that the scripts were installed.

Closes https://github.com/astral-sh/uv/issues/4691.

## Test Plan

`cargo run uv tool install ruff` (snapshot tests to-come)
