`valet uninstall` only displays information about how to manually uninstall and clean up after Valet.
This PR adds a `--force` parameter, which will forcefully remove Valet and the Homebrew services it installs, as well as clean up the config files and log files.
But for a few post-uninstall composer dependencies, cleanup is very thorough.
This brings idempotency to both `valet install` and `valet uninstall --force`
(There may still be edge cases where other Homebrew or composer packages might create interference with install/uninstall, but this makes things much easier to self-troubleshoot.)
