Add VM corruption check to verify_heapam()
Detect heap pages whose PD_ALL_VISIBLE flag is clear while either
visibility map bit is set. This inconsistent state can cause incorrect
index-only scan results and is not currently reported by verify_heapam().
This also helps users who have access to amcheck but not pg_visibility
to diagnose corruption.
