Subject: bin/brew: move logic to Library.

`bin/brew` is getting a bit bloated and it's annoying to open all of
`HOMEBREW_PREFIX` in your editor of choice and have it search through
the `Cellar`. Let's instead keep the bare minimum in `bin/brew` and
move the rest to `Library`.

Closes Homebrew/homebrew#49185.
