[Android] Properly disable the touch ack timeout during a touch sequence

This issue was recently uncovered by the interaction of touch-action:none
when disabling the touch timeout.  In that case, the disable command did not
actually take effect until the following touch sequence (if one was active).
Instead, forcefully disable the timeout/timer for the current touch sequence
when the TouchEventQueue is commanded to do so.
