Add TAP tests to check replication slot advance during the checkpoint The new tests verify that logical and physical replication slots are still valid after an immediate restart on checkpoint completion when the slot was advanced during the checkpoint. This commit introduces two new injection points to make these tests possible: * checkpoint-before-old-wal-removal - triggered in the checkpointer process just before old WAL segments cleanup; * logical-replication-slot-advance-segment - triggered in LogicalConfirmReceivedLocation() when restart_lsn was changed enough to point to the next WAL segment.
