Doc: clarify the type and meaning of QQuickMultiPointHandler::centroid
Amends 52d35526f256bf4c8155f5e660a214ab8a2efbdf : it's now a QQuickHandlerPoint
rather than QPointF, and is inherited from MultiPointHandler to DragHandler
and PinchHandler. So the docs can be inherited too, but in PinchHandler
it seems more appropriate to keep the overridden docs which explain that
transformation around the centroid depends on pinchOrigin.
Task-number: QTBUG-70074
