Fix issue with project resources overriding framework resources.

Framework resources loaded through Drawable.createFromXml could
be overriden by project resources if there were loaded through
a  state list drawable where the final resource name was used
by a project resource (of the same type).

This ensures that the XML parser knows that it's a framework
resource being parsed and that the resource resolution uses
that information.
