Beginning implementation of quickscrub (1/3)

When enabled via launcher, the home button is able to be be pulled to
the right side to send events to launcher via binder calls of when the
quick scrub operation starts, ends and progress changes between each
interval. Launcher will use this information to determine how the
recents apps are laid out with vibration feedback.

When the home button is pulled and released under 150ms, quick switch
will occur. A binder call will tell launcher to switch to the previous
app used.

While quick scrub or switch is active, launcher will not get any nav
bar motion events, only events for quick scrub and switch.
