Implement MediaStreamTrackProcessor maxBufferSize support
rdar://121256478
https://bugs.webkit.org/show_bug.cgi?id=267763
Reviewed by Eric Carlson.
We add support for buffering some video frames based on maxBufferSize using a
Deque.
The size restriction is enforced in the media pipeline to limit buffering even
if the worker thread is blocked.
We keep a maxBufferSize of 1 in Cocoa ports for camera sources since they used
a limited number of video frames so buffering could stop the camera and fail
capture.
