Move QQSinglePointHandler::acceptedButtons to QQPointerDeviceHandler

This property must exist in DragHandler, but we're preparing to have
DragHandler inherit from MultiPointHandler.  So it's no longer true
that a MultiPointHandler only handles touch events:
if minimumPointCount is set to 1, it can handle the mouse as well.
