  Make WTF_MAKE_COMPACT_TZONE_ALLOCATED set allowCompactPointers and re-enable 
TZone compactness inheritance

Reviewed by Keith Miller.

Makes it so a type declared with WTF_MAKE_COMPACT_TZONE_ALLOCATED will still
declare that it allows compact pointers, and re-lands inheritable compactness
in the TZone malloc implementation. Also unifies requiresCompactPointers() and
compactAllocationMode() so that there aren't two parallel mechanisms of
detecting compactness for a type.
