xcb: Use QWSI::handleTabletEnterLeaveProximityEvent(.. QPointingDev* ..)

Browse Source 
We want to pass the QPointingDevice* because we've already identified
it by its "system ID" (xinput device number). The other versions of
handleTabletEnterProximityEvent and handleTabletLeaveProximityEvent
try to identify the stylus by only its deviceType, pointerType and
unique ID, which can go wrong if there are multiple tablet devices and
the unique ID is not provided (as with N-trig and Wacom tablets being
used at the same time). Anyway this fixes a TODO comment from
6589f2ed0c

Leave a "deprecated" comment by the QWSI functions that should not
be used.

Pick-to: 6.6 6.5
Task-number: QTBUG-104878
