[AR] Generic Hit-testing

This changelist in 4.18 removed generic hit-testing from the AugmentedReality library -…ca926eda406264

Why? Is this not something that will be supported in 4.18? Or will it be moved to another library? Re-enabled at another time? Or should we forget about generic AR hit-testing, and just use either ARCore or ARKit plugins directly?

I would also like to know this…

Based on the updated ARSample project, I guess this isn’t supported for 4.18.
