pgstat: Prepare to use mechanism for truncated rels also for droppped rels.
The upcoming shared memory stats patch drops stats for dropped objects in a transactional manner, rather than removing them later as part of vacuum. This means that stats for DROP inside a transaction needs to handle aborted (sub-)transactions similar to TRUNCATE: The stats up to the DROP should be restored. Rename the existing infrastructure in preparation.
