FrameCadenceAdapter: ensure frame arrival after drop.

This CL accomplishes three things:

1) It enables feeding frame drop indications into the
AdaptedVideoTrackSource for the benefit of downstream projects.

2) Under zero hertz source delivery, a discarded frame ending a
sequence of frames which happened to contain important information
can be seen as a capture freeze. Avoid this by starting requesting
refresh frames after a grace period.

3) It changes the duration until first refresh frame requests on new
streams to three frame periods.
