v4: Get rid of dependency on QQuickAnchorLine type

Delegate the meta-type id query and value comparison to
QDeclarativeMetaType.

Register a comparison function for QQuickAnchorLine in
QQuickItemsModule, so that not even QDeclarativeMetaType needs to
know the type declaration. (This is needed in order to be able to
move the items to a separate library.)
