Introduce a simple version of verticalContainerReveal()

This CL exposes an initial simplified version of
verticalContainerReveal() that expands a container while dragging
vertically and plays haptics after crossing a threhsold. The goal of
this CL is to provide a first basic API for Dual Shade motion & haptics,
the motion in itself is not polished yet and will be improved in the
future with Motion Mechanics.

At the moment there is no difference between the transition on handheld
vs the transition on large screens. verticalContainerReveal() will
probably evolve in the future and require an additional parameter for
the type of screen/transition it should play.

This CL was only tested manually in the STL demo app using ag/30321185.
See b/376438969#comment7 for videos and go/stl-dual-shade for details.
