Move the simple video encoder/decoder factory from AppRTCMobile into the public API so users who don't have special requirements for video codecs can easily get started. Also clean up the API a little. This CL replaces the more flexible default factories in https://webrtc-review.googlesource.com/c/src/+/7741 and clients that want to implement their own codecs will have to supply their own encoder/decoder factories as well. The benefits of the approach in this CL are a simpler API and less effects on the rest of the code.
