Use AuthorizedProjectRefresh::ProjectCreateWorker for project create

What does this MR do?

AuthorizedProjectRefresh::ProjectCreateWorker as a specialized worker use much less resource to update project authorizations but it could lead to synchronization issues because it doesn't serialize simultaneous update events. The previous approach of AuthorizedProjectsWorker is not bulletproof either, inconsistencies do accumulate in the project authorization cache over time. For now, we also use the previous approach as a safety measure but with some delay and lower priority (AuthorizedProjectUpdate::UserRefreshWithLowUrgencyWorker).
