Renamed the WEBRTC_THIRD_PARTY_H264 macro to WEBRTC_USE_H264 to match flag name. The idea is to be able to turn off H264 from chromium with this function because... 1) The Chromium trybots will soon use this flag, we want to temporarily disable H264 from chromium even if flag is set in case something is broken. That way when we are ready to flip the switch the trybots will run our test code then and not after it is already enabled. 2) If feature is launched and we discover major problems we can easily disable H264 and merge with beta/stable. 3) Or, if feature is behind a *runtime* flag, this is how we would control if it is used or not. The idea is to call DisableRtcUseH264 in chromium's PeerConnectionDependencyFactory.
