RTCAudioSession and RTCAudioSessionConfiguration allow users to handle audio manually and is used by the AppRTCMobile example. RTCVideoFrameBuffer exposes a protocol that users can implement to create their own frame buffer formats, as long as they can be converted into i420. RTCVideoCapturer and RTCVideoViewShading are imported by other headers already included by the umbrella header, so they were always accessible to users. Added them to the umbrella header to make it explicit. BUG=webrtc:7351, webrtc:8027 Review-Url: https://codereview.webrtc.org/2994253002 Cr-Commit-Position: refs/heads/master@{#19379}
