avformat/rtpenc: Add flag AVFMT_NODIMENSIONS. Not all rtp formats require the video dimensions to be available up front. H264 and HEVC will send them as stream parameters. The flag is restrictive and prevents RTP repacketization without parsing the codec information out of the stream. This change checks to see if the codec parameters are available on the rtp formats that need it.
