Reduce surface area of MeshDescriptionProvider/Committer, replace with UE::ToolTarget:: calls where possible.
Add new UE::ToolTarget::CommitMeshDescriptionUpdateViaDynamicMesh() function. This is being used for now to avoid potential regressions as UE::ToolTarget::CommitDynamicMeshUpdate will preferentially use DynamicMeshCommitter, and I am not certain it is functionally equivalent in all cases.
Add new UE::ToolTarget::CommitDynamicMeshNormalsUpdate(), similar to existing UV version
Add new Move-variant of UE::ToolTarget::CommitMeshDescriptionUpdate(), uses new Move-variant of IMeshDescriptionCommitter::CommitMeshDescription.
Make existing IMeshDescriptionCommitter::CommitMeshDescription callback interface protected, to prevent usage of this function at public API level (will be removed in future).
Tool updates should not change, just using cleaner APIs.
EditNormalsTool now uses CommitDynamicMeshNormalsUpdate(), which does go via DynamicMeshCommitter preferentially, where it previously went via MeshDescriptionCommitter. In light testing the results appear equivalent.
AttributeEditorTool now operates on MeshDescription copies in various update functions. These are not performance-critical.

ToolsFramework:
- added new USceneSnappingManager::ExecuteSceneHitQuery API function, as well as accompanying FSceneHitQueryRequest/FSceneHitQueryResult structs
- added FSceneQueryVisibilityFilter struct which contains ComponentsToIgnore/InvisibleComponentsToInclude lists for snapping queries and provides shared IsVisible() implementation
ModelingComponents:
- add FLevelObjectsObserver, tracks Actors added/removed to a Level via various editor events
- add FSceneGeometrySpatialCache, maintains spatial data structures for known types of mesh-backed PrimitiveComponents, an octree based on their world-space bounding-boxes, and provides various spatial-query functions
- ModelingSceneSnappingManager now maintains a FSceneGeometrySpatialCache for a set of Actors/Components it is notified about, and updates the spatial cache if those components are modified or translated. Currently supports Volumes and DynamicMeshComponents.
- add ModelingSceneSnappingManager::ExecuteSceneHitQuery implementation, does raycasts into the world (for static mesh components) and FSceneGeometrySpatialCache for Volumes/DMCs
- modified ModelingSceneSnappingManager::ExecuteSceneSnapQuery to also do combined query against StaticMeshComponents via world-linetrace, and FSceneGeometrySpatialCache for Volumes/DMCs
- add ToolSceneQueriesUtil::FindNearestVisibleObjectHit variants that take a USceneSnappingManager or UInteractiveTool, and do queries via the SceneSnappingManger, instead of directly linetracing into a UWorld
ModleingToolsEditorMode:
- add FLevelObjectsObserver instance and use it to drive updates to active ModelingSceneSnappingManager
