Makoto Kato 00b8414f9b Bug 1717464 - Handle ACTION_CANCEL for TrackPad scroll. r=geckoview-reviewers,agi
This will be a bug of Android VM on Chrome OS.

When touching trackpad, Android VM on Chrome OS might fire scroll event for
trackpad, then, it fires cancel event immediately.

Actually, since we don't consider this situation, APZ detects that this is
log tap unfortunately.

So we should dispatch ACTION_CANCEL as scroll event.
