Android: Treat ACTION_CANCEL as TouchCancelEvent

Change 64d62c53c1e92a1cc07449a0ea3c71501592c1e7 started treating an
ACTION_CANCEL as a TouchPointReleased. This leads to unintentional
presses, if e.g. an edge swipe for the android back gesture starts on a
MouseArea.

When Android takes possession of the motion, an ACTION_CANCEL is
delivered, which needs to be handled as such. It should not be treated
as a normal up event that triggers a press. Otherwise, we get the
above-mentioned issue, where an unintentional action is performed.
So let's use QWindowSystemInterface::handleTouchCancelEvent to treat it
as a canceled touch in Qt.
