Add orphaned topic consistency check (#28507)
- If a topic has zero repository count, it means that none of the
repositories are using that topic, that would make them 'useless' to
keep. One caveat is that if that topic is going to be used in the
future, it will be added again to the database, but simply with a new
ID.
