Fix PanGestureDetector issue

- If the number of minimum touch is more than two, PanGestureDetector::DetectedSignal is
  not emitted because 'mState' of PanGestureDetector could not update from Clear to other states.

- When the detector state is Clear and the primary point state is stationary,
  the detector state should update Possible and Send Pan event.
