Any reason to have a separate factory for TV? (We can save 2 files if we have
ifdef in factory implementation rather than media_stream_dependency_factory.)

This factory takes pointer to MediaStreamDependencyFactory in constructor to use
as "owenership tag" which I don't think is common across all platform.
