Philipp Hancke bbff58d935 Introduce "well-known" SdpVideoFormat codecs
describing video codecs with their parameters as static members of SdpVideoFormat:
  static const SdpVideoFormat VP8();
  static const SdpVideoFormat H264();
  static const SdpVideoFormat VP9Profile0();
  static const SdpVideoFormat VP9Profile1();
  static const SdpVideoFormat VP9Profile2();
  static const SdpVideoFormat VP9Profile3();
  static const SdpVideoFormat AV1Profile0();
  static const SdpVideoFormat AV1Profile1();
This removes the need to craft instances of these by hand.
