MeshSelectionTool: enable new decomposition support to improve painting performance on large meshes. Fix code that was doing repeated linear searches to remove elements from a potentially-very-large array. Make brush-ROI tri centroid point rendering optional.

to support that: adds some support for packing multiple meshes into one dynamic mesh via a triangle attribute, a meshreplacementchange, and some improvements to the plane cut algo

- MeshDescriptionToDynamicMesh now always enables MaterialID attribute
- add FComponentMaterialSet and FComponentTarget::GetMaterialSet() that returns for current object (eg set of Material Slot materials on StaticMesh)
- move FMeshRenderBufferSet to BaseMeshSceneProxy.h, add new FBaseDynamicMeshSceneProxy, centralizes management/initialization of RenderBuffers, default GetDynamicMeshElements implementation draws buffer set returned by subclasses
- FSimpleDynamicMeshSceneProxy and FOctreeDynamicMeshSceneProxy now subclass FBaseDynamicMeshSceneProxy, implement necessary functions/etc
- UBaseDynamicMeshComponent now manages its own set of Materials. New OverrideMaterial can be set to replace existing materials with override material during render calls (does not affect material set)
- FSimpleDynamicMeshSceneProxy now builds per-material RenderBuffers, new FastUpdateVertices function to update positions/normals/colors. Removed shared-vertex construction, now only builds split-triangle buffers.
- UPreviewMesh gets wrapper functions to manage materials, override material, tangents of contained Component
