Permits measuring encoding time even when performed on another thread, typically for hardware encoding, instead of assuming that encoding is blocking the calling thread. Permitted encoding time is increased for hardware encoders since they can be timed to keep 30fps, for instance, without indicating overload. Merges EncodingTimeObserver into EncodedFrameObserver to have one post-encode callback.
