A new lit vertex color material is added and used if the ModelingComponents module is loaded (to avoid adding a new engine material, if only GeometryFramework is loaded, then the engine-default vertex color material is used). This class-wide vertex color material can be overridden via UBaseDynamicMeshComponent::SetDefaultVertexColorMaterial()
Facet Normals / Flat Shading is now separately configurable, this overrides the normals at the vertexbuffer setup level, so it works independently of material.
Support also added for configuring the wireframe material used for BaseDynamicMeshComponent, and also for setting the wireframe color.

GeometryCore: Add bClearExisting option to FDynamicMeshAttributeSet::EnableMatchingAttributes(). Default true is old behavior. New behavior, when false, is to preserve existing attribute set counts/values. Also now copying group and weight layer names if not set.
ModelingTools: CombineMeshesTool now uses EnableMatchingAttributes instead of only explicitly matching UV layers, so group and weight layers are copied properly to duplicates
MeshConversion: DynamicMeshToMeshDescription now generates unique names in ConvertPolygroupLayers and ConvertWeightLayers. Previously if multiple attribs had the same name (eg NAME_None), output MeshDescription would only have a single attrib w/ that name

- add FQueueRemesher::MinActiveEdgeFraction. If fraction of modified/total edges in remesh pass is below this parameter (default 1%), consider result converged.
- Expose as option in FRemeshMeshOp, and add sane defaults for all parameters of Op
- move CalculateTargetEdgeLength function from RemeshMeshTool to static function in FRemeshMeshOp, update Tool
- add Geometry Script function ApplyUniformRemesh

Tidy up use of FPrimitiveSceneProxy velocity getters.
Now DrawsVelocity() is only for velocity relevance.
And HasDynamicTransform() is for determining if we need to store previous transform state.
VSM caching was using PRIMITIVE_SCENE_DATA_FLAG_DRAWS_VELOCITY so replaced that with PRIMITIVE_SCENE_DATA_FLAG_SHOULD_CACHE_SHADOW which should use the old behavior and can be tweaked in future using ShouldCacheShadow().
A common pattern for determining whether to output velocity now is to check if a previous transform exists, and to OR in AlwaysHasVelocity().
I found some proxy types that don't check for previous transform.
Also I found that the debug physics aggregate types *never* check for previous transform.
These are pre-existing potential bugs for fixing in another pass.
Also I found some proxies that don't currently fill out velocity relevance.
