Optimize the origin drop functionality.
To interlock against concurrent drops, we use to hold ExclusiveLock on
pg_replication_origin till xact commit. This blocks even concurrent drops
of different origins by tablesync workers. So, instead, lock the specific
origin to interlock against concurrent drops.
This reduces the test time variability in src/test/subscription where
multiple tables are being synced.
