Remove statuses that are not referenced by local user activity, such as
ones that came from relays, or belonging to users that were once followed
by someone locally but no longer are.
It also removes orphaned records and performs additional cleanup tasks
such as updating statistics and recovering disk space.
This is a computationally heavy procedure that creates extra database
indices before commencing, and removes them afterward.
