make the QTouchDevice available in each QNativeGestureEvent

QtQuick is beginning to have a use for this, to distinguish native
gestures which come from actual trackpad rather than from the "core pointer".
It might as well use a real device ID instead of making one up,
as it has to do for the core pointer.

So far on macOS, the device ID isn't a real one; but that can be fixed,
as the qCDebug lines demonstrate (different trackpads have different IDs).
