In https://gitlab.com/gitlab-org/gitlab/-/merge_requests/77908 we
already added a ["loose foreign key"](
https://docs.gitlab.com/ee/development/database/loose_foreign_keys.html)
to replace this foreign key. Now that this has been running fine in
production we should be OK to remove the foreign key altogether.

This was added in a post-deployment migration as we want to ensure that
they have the correct code running with the loose foreign key in place
before we remove the foreign key to ensure that there isn't any lost
deletes.

Add package file cleanup jobs

See merge request gitlab-org/gitlab!77212

- Add a cron job and a limited capacity worker to delete package files
  in a decoupled and async way, taking the Package Registry a step
  closer to a scalable package file deletion approach.
- The cron job runs twice a day. It checks if there are any package
  files pending destruction, in which case it enqueues the limited
  capacity worker.
- The limited capacity worker picks up and destroys package files that
  are pending destruction one by one until all have ben deleted.
- Since the new jobs are very similar in functionality to the Dependency
  Proxy cleanup jobs, do some refactoring for reuse.
