(Only) poison unmarked heap objects prior to sweeping.

Drop the unnecessary restriction that eagerly finalized objects aren't
allowed to touch access other eagerly finalized, but live, objects during
finalization. They're allowed to access live objects in other heaps/arenas,
so the same-heap restriction makes little sense.

Simplify the HeapPage poisoning methods as a result.
