Might be nice to update VideoDecoderConfig to use one of these later.

I actually tried to add level to VideoDecoderConfig, but it was a pretty ugly
and massive change. Most users of VideoDecoderConfig don't care about level and
its constructor already has over 10 parameters. Dale recommended a new struct
like you see here. Down the road  MediaCapabilities queries will continue to
grow to contain things not needed/wanted in VideoDecoderConfig.
