Add package registry cleanup rules (#21658)

Fixes #20514
Fixes #20766
Fixes #20631

This PR adds Cleanup Rules for the package registry. This allows to
delete unneeded packages automatically. Cleanup rules can be set up from
the user or org settings.
Please have a look at the documentation because I'm not a native english
speaker.
