Plan will be as follows:
- Associate an origin with a MediaSinksObserver.
- Modify sink list updates to include a list of origins for which the sink list is valid. The list of origins will be used to determine whether a given MediaSinksObserver has access to the updated list. We will use an empty origin list to denote that the result is valid for all origins.
