Re: [webrtc-svc] https://w3c.github.io/webrtc-svc/#rtcrtpcodeccapability* is redundant with https://w3c.github.io/media-capabilities/#dom-videoconfiguration-scalabilitymode (#49)

Media Capabilities exposes hardware info so it needs privacy mitigation, precisely to prevent iterating over every possible combination of codecs, hardware support, etc.  Since SVC is rarely supported in hardware (WebCodecs is shipping with no hardware support, currently), WebRTC-SVC doesn't have the same level of privacy concerns. Since getCapabilities() provides other related information such as header extension support (important for negotiating forwarding header extensions), the application need to call getCapabilities() anyway, so it might as well get all the information in a single call.
