Media Info API example for bitrate metrics

The recent QoE standard in progress requires access to the currently playing bitrate, to calculate bitsPlayed. This isn't easy to get on the web currently. One of the requests at FOMS was something like a Media Info API (similar in concept to the Media Capabilities API) that could provide those details. A request from browser developers was an example of what we would want to see from this API.

So we should create an example of what we think the API could look like. The action item included @robwalch.

A few suggestions from Eric Carlson and others at apple:

Check out WebRTC Stats API for an example of similar stats already made available by the browser.
Look to the Intersection Observer API as a better example of an API where you tell the browser what details you want. Otherwise the browser has to dig into the system to get all the info each time which is costly.
Look at AV Player HLS stats for example of what people have asked for from that API.

This has been kicked around a few repos looking for a home. Felt like video-dev should have a spot for discussions like this.
