Only allow heap in a number of contrib modules.

Browse Source 
Contrib modules pgrowlocks, pgstattuple and some functionality in
pageinspect currently only supports the heap table AM. As they are all
concerned with low-level details that aren't reasonably exposed via
tableam, error out if invoked on a non heap relation.
