This makes me think RegisterWIthClient should be given a more explicit name (at
least mention resources?).  Or scope it with the class name here.  When you're
just reading CmaMediaPipelineClient, this callsite is pretty mysterious.

Done. Scoped it with class name. Also added comments to
CastResource::RegisterWithClient. Hope that helps a little.
