[lworld] RFR: 8374882: [lworld] Update hierarchies in oopsHierarchy.hpp

[Joel Sikström]

Hello,

The hierarchies in oopsHierarchy.hpp are not up to date with the actual class hierarchies in the implementation. I've refered to these a couple of times and stumble on the fact that they are not accurate.

I've tested that this builds locally.
