Revert "Move rtp-specific config out of EncoderSettings."

This reverts commit bc900cb1d1810fcf678fe41cf1e3966daa39c88c.

Reason for revert: Broke downstream projects.

Original change's description:
> Move rtp-specific config out of EncoderSettings.
> 
> 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.
>
