Introduces haptic feedback to launcher overview

Browse Source 
Haptics introduced at the key moments:

- Task scroll in overview or quick switch, trigger when a new task comes
to the center of the screen;
- Task scroll in overview when overscroll animation is triggered;
- Task dismissed in overview;

There is also a configured min gap between two scroll haptics set to
20ms to prevent fast scrolls from creating a chain of cancelled effects.
