Core: Remove 'properties' feature

Even QtCore alone cannot be built without the properties feature since
Qt 5.5. While fixing this is easy, other modules like dbus,
networking are also using QObject::property() and friends liberally.

All in all I doubt that anybody will miss the feature (otherwise it
would have been fixed in the last decade).
