Settings Switch animation jank while enabled One-handed mode

Switch is CompoundButton(View) and animating position when user
tap on it. Unfortunatly when set overlay pakcage enabled, Switch
componet will invoke onLayout() and cancelPositionAnimator(),
that result the UX feel jank.

We add a delay(250ms) before execute runtime resouce overlay
to ensure the widget animation finished first.

Test: Manual Settings > Gesture > One Handed Mode > Tap Switch
