Reviewed by Eric Carlson.

Expose focusDistance to allow web developers to disambiguate between various cameras.
In macOS/iOS, we can use https://developer.apple.com/documentation/avfoundation/avcapturedevice/3751762-minimumfocusdistance?changes=_5, which we can expose as focusDistance.min. We do not have a focusDistance.max so we leave that field undefined.
To do so, we use numeric_values<double>::max as the undefined value.

Covered by updated layout test and updated mock camera.
Mock front camera does not have any focus distance info and mock back camera has min focus distance of 0.2.
