Web Spec and C++ version of setCodecPreferences are failable, as they return an RTCError (in C++) or throw an InvalidModificationError (in Web Spec). However, current Objective-C version of setCodecPreferences is not failable, so callers cannot know if the operation succeeded or not. Also, the current Objective-C version does not accept nil, which is not spec-compliant. (Web Spec says if codecs is an empty list, set transceiver.PreferredCodecs to codecs and abort these steps.)
