Avoid changing transform when touching in progress

After swiping from a landscape app to portrait home, the touch
orientation may be changed if there the touch event comes in a
short time (e.g. click app icon immediately):
 DOWN
 MOVE...
 SimpleOrientationTouchTransformer#onDisplayInfoChanged
 MOVE... (start to transform with inconsistent orientation)
 UP

That could disturb the gesture detection:
OverviewInputConsumer#onMotionEvent
 > BaseDragLayer#proxyTouchEvent
  onInterceptTouchEvent, findControllerToHandleTouch
  > PortraitStatesTouchController#onControllerInterceptTouchEvent
   > BaseSwipeDetector#onTouchEvent
which may show the app drawer unexpectedly.
