This adds LOD visibility for xr-iframe's extents. It honors the extents and load-distance for xr-iframe at the engine level, and also accounts for layered XROffset transforms:
The default remains visibility for all xr-iframes and the default load-distance is Infinity. load-distance of 0 means exactly the extents bound, while load-distance === 10 means load when <= 10 units away.
