Re: [webrtc-pc] Add video latency constrainable property (#2109)

> Yes, it should fire. And, BTW, Chrome is implementing that behavior.

@guidou When I [try it](https://jsfiddle.net/jib1/x7r4pknu/) in Chrome I get `applyConstraints not supported for this track`:
```
getSettings: {"deviceId":"b88716e4-4d43-45d3-8a96-6b6748a6a7ad","resizeMode":"none"}
getCapabilities: {"deviceId":"b88716e4-4d43-45d3-8a96-6b6748a6a7ad","facingMode":[],"resizeMode":["none","crop-and-scale"]}
OverconstrainedError: applyConstraints not supported for this track
```
I get similar output in Canary except it crashes. Is it behind a pref?

FWIW, I would not expect a peer connection to have a `deviceId`, nor mention capabilities that do not make sense, like `facingMode`. [resizeMode](https://w3c.github.io/mediacapture-main/getusermedia.html#def-constraint-resizeMode) mentions camera. A peer connection is not a camera.

Basically, this is not what I expected to see, so I think we need to specify this. I've opened https://github.com/w3c/webrtc-pc/issues/2121. Let's discuss there, and leave this issue to discuss the merits of video latency for remote tracks.
