[Android] Send TapCancel if necessary when a touch gesture is consumed

[Android] Send TapCancel if necessary when a touch gesture is consumed

When a TouchStart is unconsumed by Javascript, a GestureTapDown is sent
immediately, potentially followed by a GestureShowPress.  Fix the case where
the subsequent Touch{Move,End} is consumed by Javascript by synthesizing
a GestureTapCancel.
