There is a case when one handed mode triggered(Activated), all apps
drawer is very easy to trigger while user swipe up around NavBar
region to exit one handed mode. Since System Gesture monitor regsion
is small on screen bottom, swipe-up gesture usually cross over NavBar
monitor region and invoke launcher touch controller intercept touch
event and introduce unexpectedly trigger all apps drawer.
Adding onOneHandedModeStateChanged(boolean activated) for controller
be able to adjust the touch slop by multiplier, we can set a larger
multiplier when the visible window size translate become smaller
and make swipe gesture not too sensitive.
Test: manual swipe up to swich "home <-> all apps" and monitor
minDisplacement of SingleAxisSwipeDetector
Test: Trigger one handed mode and swipe up to exit one handed mode
check the minDisplacement of SingleAxisSwipeDetector
