Move rtp-specific config out of EncoderSettings.

Browse Source 
In VideoSendStream::Config, move payload_name and payload_type from
EncoderSettings to Rtp.

EncoderSettings now contains configuration for VideoStreamEncoder only,
and should perhaps be renamed in a follow up cl. It's no longer
passed as an argument to VideoCodecInitializer::SetupCodec.

The latter then needs a different way to know the codec type,
which is provided by a new codec_type member in VideoEncoderConfig.
