The [constrainable pattern](https://w3c.github.io/mediacapture-main/getusermedia.html#constrainable-interface) appears to force our hand here. It has no concept of read-only constrainable properties, which I think means that if we want to humor that pattern, we must define these as *constrainable properties* (and ignore/throw `OverconstrainedError` on changes to them), for POLA.

That said, good observation that we're not extending `MediaTrackSettings`, which we should. We need to extend all 4 dictionaries mentioned in the [extensibility section](https://w3c.github.io/mediacapture-main/getusermedia.html#defining-a-new-constrainable-property).
