This CL introduces SurfaceReferenceFactory which can create surface references
while hiding the implementation details from its client. So the client cannot tell if the
underlying implementation is SurfaceSequence or SurfaceReference, which paves the
way for replacing SurfaceSequence with SurfaceReference. All require / satisfy
callbacks are now gone and are replaced with different implementations of
SurfaceReferenceFactory.

This CL also adds SurfaceInfo, which contains information
about an embedded surface that are usually passed around together.
