applist: Add a metrics for homescreen animation smoothness.
This will help with future work for improving smoothness of animation
and drag. Adds a UI interactive test as well. A tast test was underway
but due to having to wait until new uprevs as well as apis still
underway (launcher, accelerator autotest private api) i think the
interactive UItest still has some values.
Test: added tests
