Re: [mediacapture-image] Determine how PTZ permission prompts are supposed to work (#243)

Spec [says](https://w3c.github.io/mediacapture-image/#tilt) for tilt for instance:

> Any algorithm which uses a MediaTrackConstraintSet object and its tilt dictionary member which exists after a possible normalization **MUST request permission to use** (as defined in [permissions]) a PermissionDescriptor with its name member set to camera and its panTiltZoom member set to true, and, optionally, consider its deviceId member set to any appropriate device’s deviceId."

Would it help if we were indicating that if gUM requests ptz capability, and a device with the capability is selected, it should prompt for that permission?
Or maybe instead of saying "any algorithm", we could link to a specific section about gUM.
