MeshSceneAdapter: handle mis-configured MeshDescription material slot names that reference ImportedMaterialSlotName instead of MaterialSlotName, and fall back to material 0 / default surfarce material in cases where material is not defined (which is normal engine behavior elsewhere). Add CVar to control multi-threading, to support debugging. Fix handling of nearly-thick-enough objects that were incorrectly being converted to very thin shells.
ApproximateActors: Expose options for ground plane clipping, UV generation method, tiny parts filtering, implement support for these options. Add optional base-plane occluder to allow occlusion filtering to remove "bottom" geometry. Implement fallback to Boxmap UVs if UV generation fails. Set default output material on generated Collision meshes.
Expose above options in FMeshApproximationSettings for MergeActors/etc UI
