Handle 2d sites passed into Exokit

Currently passing in sites as arguments will load if they are 3d sites, should Exokit detect and load 2d sites?

That could be a reasonable feature. I'm just not sure what the use case is.

Would it be opening as a reality tab, or would be just be being chrome?

What about VR entry buttons? We'd probably want that to function if we're doing this, but that would require a complicated heuristic dance between chrome and exokit.

It makes sense to have it open in a 3d world as a 2d reality tab, otherwise it would be going into normal 2d browser territory.

Users would also presumably be able to exit that specific layer back to 2d mode from VR mode.
