Add AndroidVideoSurfaceChooser to manage overlays.

This CL abstracts out much of the surface-switching logic from AVDA
into AndroidVideoSurfaceChooser.  It also handles talking to overlay
factories that will be provided by the renderer.

AndroidVideoSurfaceChooser notifies AVDA about when to transition to
/ from an overlay.  Currently, this is based only on whether the
renderer has provided an overlay factory or not.  In the future,
this will look at compositor feedback and other hints to decide.

This CL also adds lots of tests for this behavior.  Previously, it
wasn't easy to test surface transitions since (a) they were bundled
into AVDA itself, and (b) they directly depended on hard-to-mock
classes like ScopedJavaSurface.  Now, AndroidVideoSurfaceChooser
abstracts the logic, and AVDA no longer directly deals with any of
those hard-to-mock objects.
