Mark stationary touch points as updated if pressure or velocity changes
This is to inform Qt Quick when a stationary touchpoint is delivered
that it is because of a changed property. Qt Quick still needs to avoid
delivering item-customized events (with only the touch points that occur
inside the item) that contain only stationary touch points without
changed properties. To be able to check this private flag,
QQuickPointerTouchEvent needs to be a friend.
