Improve TransactionIdDidAbort() documentation.

Document that TransactionIdDidAbort() won't indicate that transactions
that were in-progress during a crash have aborted.  Tie this to existing
discussion of the TransactionIdDidCommit() and TransactionIdDidCommit()
protocol that code in heapam_visibility.c (and a few other places) must
observe.

Follow-up to bugfix commit eb5ad4ff.
