improved tap suppression change
The touchpad can deliver multiple GestureFlingCancel events within the
time window in which we would like to continue to suppress mouse events
after the GFC that actually halted the in-progress fling. This change
makes the TapSuppressionController stop resetting its state machine
on the receipt of such events such that tap suppression continues
throughout the time window following a fling-cancelling GFC regardless
of intervening GFC events.
