ryan schmidt a8da674d2c ApproximateActors: Implement support for detection of thin-slabs (ie thin planar meshes that are not single-sided) in FMeshSceneAdapter. Add support for sub-mesh instancing, to reduce number of times that repeated meshes are unique'd when used with the same scaling transform. Reorganize computation so that spatial builds are processed in decreasing-mesh-size order, and do other parallel improvements, such that time to process a large assembly (total ~2.2b triangles from 37k instances of 415 unique meshes w/~44m unique triangles) reduces from 58s to 22s (with ~10s of this time being loading source mesh data) on 64-core threadripper.

Move ConvexHull2, ConvexHull3, and exact predicates into GeometryCore/CompGeom. Change them all to use the UE::Geometry namespace. Copy associated TPS files as needed.
