Add helper for freeze determination to heap_page_prune_and_freeze

After scanning the line pointers on a heap page during the first phase
of vacuum, we use the information collected to decide whether to use
the assembled freeze plans.

Move this decision logic into a helper function to improve readability.

While here, rename a PruneState member and disambiguate some local
variables in heap_page_prune_and_freeze().
