[Android] Backport Chromium r237215

This is to fix crash when multi touch on Android devices
previous to 4.2.2.

Origin commit log:
    [Android] Record MotionEvent times for pre-4.2.2 ScaleGestureDetector bug.

    Android's pre-4.2.2 ScaleGestureDetector failed to properly record MotionEvent
    times.  This leads to problems, as the detector's event time is used to assign
    the synthesized gesture event time.  Record the MotionEvent time prior to
    feeding it to the ScaleGestureDetector.
