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

USceneSnappingManager currently only provides the current snapping interface and a no-op implementation.
Move existing EdModeInteractiveToolsContext snapping implementation to ModelingSceneSnappingManager in ModelingComponents module.
Add IContextQueriesAPI::GetCurrentSnappingSettings to allow ITF Host to specify snapping settings, implement in EdModeInteractiveToolsContext.
Update affected Tools/Gizmos, register ModelingSceneSnappingManager instance in Modeling EdMode.

- UPersistentMeshSelection is largely a port of UGroupTopologyStorableSelection, with the actual selection data moved to FGenericMeshSelection
- UPersistentMeshSelectionManager is meant to be used as a ContextObject in a ToolsContext, also contains utility functions to register/unregister/find context object
- Selection is no longer passed as part of FToolBuilderState. Instead Tools access the selection via ContextObject
- UPersistentMeshSelectionManager currently supports a single active selection. Selection changes are transacted via an FChange.
- When not inside a Tool, Selection is visualized with a pink border outline. Currently vertex selection is not visualized.
- Usage model is that on Tool Accept/Complete, prior to Tool Shutdown, any existing selection is cleared, and Tool may set a new Output selection which becomes the active selection
- StoredMeshSelectionUtil.h has utility functions to get current selection, set output selection, and clear it
- SingleSelectionMeshEditingTool already made input selection available to subclasses, port that capability to new architecture
- convert EditMeshPolygonsTool to be a SingleSelectionMeshEditingTool, use provided Input selection and set Output selection as appropriate
- ModelingToolsEditorMode clears active selection where appropriate, eg if selected object changes. However the behavior here will need further improvement, currently relies on questionable event handling from the TypedElement system
