Resolve member expressions of QObject members

...when the base is a QObject property itself or an ID referenced object.

This patch resolves for example the width property in a parent.width expression
to be a per-index lookup at run-time. That requires the base ("parent") however
to be a final property or come from an object where expected revision is known, i.e.
a QML imported object (scope or context).
