webrtc/api/video_codecs/vp9_profile.h
Johannes Kron c3fcee7c3a Move h264_profile_level_id and vp9_profile to api/video_codecs
This is a refactor to simplify a follow-up CL of adding
SdpVideoFormat::IsSameCodec.

The original files media/base/h264_profile_level_id.* and
media/base/vp9_profile.h must be kept until downstream projects
stop using them.
