Add support for setting CSRCs on audio and video senders

This is a modified version of
https://webrtc-review.googlesource.com/c/src/+/392940 to avoid breaking
downstream dependencies.

With this change, CSRCs can be added to video packets sent via
RTPSenderVideo::SendEncodedImage. This is implemented by keeping a list
of CSRCs in the calling class RtpVideoSender, which is included in all
calls to SendEncodedImage. Similarly, a list of CSRCs for audio packets
is kept on ChannelSend and added to calls to SendRtpAudio. CSRCs are
also propagated to frame transformers for audio and video.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
