Speed up property binding initialization on object creation
Avoid repeated string hashing and lookups in the property cache in order to
retrieve the property details when initializing literal and script bindings.
Instead we now cache the property data at type validation time, similar to how
the property data was encoded in the VME instructions in the old engine.
