Add functions to report normalized positions in QTouchEvent::TouchPoint

This introduces normalizedPos(), startNormalizedPos(), and
lastNormalizedPos() in QTouchEvent::TouchPoint, and must be set by the
implementation before being fed into Qt.

We are assuming and hoping that these functions will make it easier to
implement certain types of gestures (especially on a touchpad).
