Remove QQuickPointerEvent etc.; deliver QPointerEvents directly

QEventPoint does not have an accessor to get the QPointerEvent that it
came from, because that's inconsistent with the idea that QPointerEvent
instances are temporary, stack-allocated and movable (the pointer would
often be wrong or null, therefore could not be relied upon).
So most functions that worked directly with QQuickEventPoint before
(which fortunately are still private API) now need to receive the
QPointerEvent too, which we choose to pass by pointer. QEventPoint is
always passed by reference (const where possible) to be consistent with
functions in QPointerEvent that take QEventPoint by reference.

QEventPoint::velocity() should be always in scene coordinates now, which
saves us the trouble of transforming it to each item's coordinate system
during delivery, but means that it will need to be done in handlers or
applications sometimes.  If we were going to transform it, it would be
important to also store the sceneVelocity separately in QEventPoint
so that the transformation could be done repeatedly for different items.
