xcb: Adapt QXcbWindow::startSystemResize() for touch events
Window managers typically grab the pointer after receiving
the _NET_WM_MOVERESIZE event. But they fail to do it for
touch sequences which have a receiver. So we should reject
the touch sequence before sending _NET_WM_MOVERESIZE event.
QSizeGrip calls startSystemResize() on MouseButtonPress event
which is synthesized by Qt on TouchBegin. We can find the id
of the touch point by comparing coordinates of the synthesized
MouseButtonPress event with coordinates of all TouchBegin events.
Then we use this id to reject the touch sequence (it's possible
only after receiving XI_TouchUpdate).
