pgsql: Cross-check lists of predefined LWLocks.

Cross-check lists of predefined LWLocks.

Both lwlocknames.txt and wait_event_names.txt contain a list of all
the predefined LWLocks, i.e., those with predefined positions
within MainLWLockArray. It is easy to miss one or the other,
especially since the list in wait_event_names.txt omits the "Lock"
suffix from all the LWLock wait events. This commit adds a cross-
check of these lists to the script that generates lwlocknames.h.
If the lists do not match exactly, building will fail.
