Misc bug fixes/features for webcodecs/VideoEncoder

• don't clear the error callback prior to calling it
• implement encodeQueueSize to signal backpressure
• add extra error logging for VpxVideoEncoder
• disable vp9 profiles 1 and 3 (not yet implemented)

And opportunistically mark a number of inputs
in IDL as required

• timestamp (its required for creation of VideoFrame internally)
• error and output callbacks (duh).

Remove ? from duration input dictionary. Its not required,
no need to null.
