Implement QQmlPropertyValueSource
As is done with the other interfaces, add a class
QPyQmlPropertyValueSource inheriting from QObject and
QQmlPropertyValueSource. Store its offset in
QQmlPrivate::RegisterType::valueSourceCast if it is found as a base
class.
[ChangeLog][PySide6] class QPyQmlPropertyValueSource for
implementing QML value sources for properties has been added.
Task-number: PYSIDE-1709
