Move RegisterValue,Scalar,State from Core to Utility

These three classes have no external dependencies, but they are used
from various low-level APIs. Moving them down to Utility improves
overall code layering (although it still does not break any particular
dependency completely).

The XCode project will need to be updated after this change.
