heapam: Move logic to handle HEAP_MOVED into a helper function

Before we dealt with this in 6 near identical and one very similar copy.

The helper function errors out when encountering a
HEAP_MOVED_IN/HEAP_MOVED_OUT tuple with xvac considered current or
in-progress. It'd be preferrable to do that change separately, but otherwise
it'd not be possible to deduplicate the handling in
HeapTupleSatisfiesVacuum().
