Unify access to SDP codec parameters

which come from the a=fmtp:<pt> lines in the SDP and were used as either
  std::map<std::string, std:string>
with three aliases,
  cricket::CodecParameterMap
  SdpAudioFormat::Parameters
  SdpVideoFormat::Parameters

Use webrtc::CodecParameterMap in all places.
