- 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

- add FColliderMeshProjectionTarget to allow a FColliderMesh to be used as a projection target
- remove dead code from TDenseGrid3
- add TBlockedDenseGrid3, variant of TDenseGrid3 that lazy-allocates sub-blocks of a dense grid, to reduce memory usage in sparse/narrow-band situations on large uniform grids
- replace usage of TDenseGrid3 in FMarchingCubes with TBlockedDenseGrid3, to reduce memory footprint on large meshing problems

This slightly improves the UX when inserting edge loops because the retriangulation option works in a more intuitive way when face groups are planar
