This code was reviewed here https://p4-swarm.epicgames.net/reviews/25007278 but that CL was into //UE5/Main. We want the change to be into //Fortnite/Main, hence this CL

Base class is changed to USingleTargetWithSelectionTool.
When selection is provided, a UPreviewMesh for the unselected area is created and used.
A FSharedConstDynamicMesh3 is used to wrap either the original mesh or the selected submesh, and passed to the Operator (which also now takes a FSharedConstDynamicMesh3)
On shutdown, modified submesh is re-integrated into original mesh (in this case a trivial group copy suffices) and a new selection is emitted

Made FSceneCapturePhotoSetSampler explicitly non-copyable to prevent its special member functions being DLL-exported.

Add IGeometrySelectionTransformer::PreviewRender() API, for rendering info during selection transforms. Currently being called by UGeometrySelectionManager::DebugRender() for active transforms.
FBasicDynamicMeshSelectionTransformer implements PreviewRender, draws selected mesh edges (tris as edges) and vertices, as well as affected edge ROI.
FDynamicMeshPolygroupTransformer overrides this behavior and draws polygroup edges/verts and edge ROI
FStaticMeshSelector and FVolumeSelector now create FDynamicMeshPolygroupTransformer for polygroup selections
FBasicDynamicMeshSelectionTransformer::bEnableSelectionTransformDrawing flag controls whether this edge drawing is enabled. Disabled on DynamicMeshComponent, enabled on StaticMesh and Volume.
Add Normals recomputation during tri and polygroup transforms in FBasicDynamicMeshSelectionTransformer and FDynamicMeshPolygroupTransformer
Add FGroupTopologyDeformer::EnumerateROIEdges() util function to support above
