Move new LOCKTAG_DATABASE_FROZEN_IDS to end of enum LockTagType.
Several PGXN modules reference LockTagType values; renumbering would
force a recompile of those modules. Oversight in back-patch of today's
commit 566372b3d6435639e4cc4476d79b8505a0297c87. Back-patch to released
branches, v12 through 9.5.
Reported by Tom Lane.
