Works by trying a bunch of plane cuts to break reduce the volume of the convex pieces, then merging them back together to remove those that were not helpful. We need the merge step especially for meshes where it takes multiple plane cuts to start reducing the hull volumes, as the initial cuts in that case are not informed by the error metric.

- Allow the Attribute Editor Tool to add/delete weight maps from DynamicMesh targets.
- Enable transferring scalar weight maps back and forth between DynamicMesh and MeshDescription.
- Serialize TDynamicAttributeBase::Name when its subclasses are serialized

- fix bug with detection of vertices on the solid segment of a ghost triangle
- detect when 'fill' of a triangulation is ambiguous under winding rules (e.g. due to open edges)
- optionally automatically track duplicate vertices and remap duplicate-vertex references to the vertex that was actually inserted

[CL 19521151 by Jimmy Andrews in ue5-main branch]
- Report failures to constrain edges, optionally detecting the case where the edge was flipped away by a subsequent constraint (happens if the constraint edges intersect)
- Add options to directly triangulation TPolygon2 and TGeneralPolygon2 (+ the supporting fill algorithms to be run on any array of edges)
- Add validation of Delaunay property for CDTs on all non-constrained edges
- Update edge cache (if enabled) on sub-triangulation append, improving perf on CDTs with many constrained edges
add corresponding test coverage, and change the test runner to always automatically run exact predicates globalinit

- Support InCircle
- Support float as well as double
- Add safer, templated versions that specify whether float or double is to be used (for TVector/TVector2)

- add FStaticMeshLODResourcesAdapter in MeshConversions module, wrapper that presents StaticMesh LODResources mesh (ie Section buffers) with an API compatible with GeometryCore mesh templates
- add TMeshWrapperAdapterd in GeometryCore, this is a shim for getting any template-API-compatible mesh into a FTriangleMeshAdapterd specifically (required to call some non-template mesh processing functions)
- add support for using StaticMesh LODResources meshes in FMeshSceneAdapter instead of source meshes, controlled by build options flag
- add FMeshSceneAdapter build options flags specifying whether UV/Normal queries are required (default true)
- when not required, the loaded MeshDescriptions and created DynamicMeshes are packed into FColliderMesh which has a smaller memory footprint, allowing the larger meshes to be freed
- to support above, the SpatialWrappers in MeshSceneAdapter.cpp have been refactored extensively
- added FCompressedMeshSpatialWrapper which Builds from a temporary FDynamicMesh3 into a FColliderMesh, supports all the same options as FDynamicMeshSpatialWrapper (so a drop-in replacement with less memory usage, but no UV/Normal queries)
- added FBaseMeshSpatialWrapper, base class for existing FDynamicMeshSpatialWrapper and new FCompressedMeshSpatialWrapper that has shared config settings (can more more here in the future)
- added FStaticMeshLODResourcesMeshSurfaceAdapter, similar toFMeshDescriptionTriangleMeshSurfaceAdapter, a mesh adapter that filters out any geo that doesn't have a Surface-domain material
- refactored TStaticMeshSpatialWrapper into TStaticMeshSpatialWrapperBase and subclasses FStaticMeshSourceDataSpatialWrapper and FStaticMeshRenderDataSpatialWrapper, for source mesh vs render mesh
- added FCompressedStaticMeshSpatialWrapper, variant of FStaticMeshSourceDataSpatialWrapper that stores to a FColliderMesh and releases the source MeshDescription
- SpatialWrapperFactory() now has logic to build from render mesh vs source mesh vs compressed source mesh
- moved initial SpatialWrapper construction from AddActors() phase to Build() phase, because now it depends on build settings
- add EMeshDataSourceLODPolicy to IGeometryProcessing::FOptions, with LOD0 Source and LOD0 RenderMesh options
- ApproximateActorsImpl now provides/handles this policy setting, and configures FMeshSceneAdapter to not need UV/Normal queries (not required in this context)
- add bUseRenderLODMeshes option in FMeshApproximationSettings to expose render vs source mesh control at user level
