Refactor FrameCandenceAdapter to keep track of input frame rate. Also a field trial WebRTC-FrameCadenceAdapter-UseVideoFrameTimestamp is added to control if VideoFrame timestamp should be used or local clock when calculating frame rate. Uma is recorded to tell if input frame timestamp is monotonically increasing.
