GeometryFlow:
Add TSwitchNode node, uses internal integer to select one of N inputs (N is currently defined in template type, so number of inputs is fixed). Add custom util function UpdateSwitchNodeInputIndex() to simplify changing switch integer.
Add FMeshMakeCleanGeometryNode/Settings, strips out undesired attribute sets and fills small holes, to create better input mesh for simplification
Add FSimpleInPlaceProcessMeshBaseNode, just runs some basic geometry operation, makes it easier to make new nodes. Converted FComputeMeshPerVertexOverlayNormalsNode to this base class and added FComputeMeshPerVertexNormalsNode.
Fixed attribute set handling issue in FSimplifyMeshNode
MeshLODToolset:
Added ECoreMeshGeneratorMode enum to FGenerateMeshLODGraph. This setting drives a Switch node that picks between Vox, Vox+Closure, and Simplify-only mesh generation paths.
Added SourceMeshHint to BuildGraph, allows for variable graph construction. Use to skip MaterialID transfer in single-material case.
Change default collision type to aligned boxes (fast and low visual complexity)
Exposed top-level Mesh Generation type, Normals settings in Graph/Process/Tool, minor UI and default changes

- DebugDumpGraph was being called before texture baking nodes were in the graph
- Fix some capitalization of tool properties
- Added some code comments
- If morphology distance is zero, don't apply it

GeometryFlow: Added FCompactMeshNode, FComputeMeshPerVertexOverlayNormalsNode (convenient), and FTransferMeshMaterialIDsNode that applies FMeshAttributeTransfer based on two input meshes. Graph InferConnection() now is more clever and can infer connections in cases where a potentially-ambiguous connection is resolved based on what is already connected (ie if two mesh inputs, and one is assigned, infer that second one is intended)
LODToolset: LODGraph now transfers materials and computes per-vertex normals before Simplify node, and Compacts afterwards (required for other downstream processes).
LODProcess now handles multiple materials, and can re-use input materials if they do not require a baked texture or normal map. In repeat applications, previously-auto-generated StaticMesh Materials are detected and removed from the material set. Normals and Tangents are explicitly computed for stored HiRes source and LOD0, and build settings updated appropriately.
