This reverts commit d427e83a15.
Reason for revert: Flaky test fixed.
Refactor FrameCandenceAdapter to keep track of input frame rate. This fixes an issue where frame rate is calculated too low if congestion window drop a frame.
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.
