ToolsFramework:
add UInteractiveCommand and UInteractiveCommandArguments types, base classes for 'interactive commands' which are intended to be used for atomic actions, ie stateless, no user interaction, etc
ModelingComponents:
add UGeometrySelectionEditCommand/Arguments, this is a UInteractiveCommand that uses a FGeometrySelection as an argument
add UGeometrySelectionManager::CanExecuteSelectionCommand() and ExecuteSelectionCommand()
MeshModelingTools:
add UDeleteGeometrySelectionCommand, deletes selected mesh geometry by converting input selection to list of triangles
ModelingToolsEditorMode:
add Delete command to ModelingMode and UI. ModelingToolsEditorMode currently is keeping active command set alive via new UModelingToolsEditorMode::ModelingModeCommands member.

New UModelingSelectionInteraction provides click-to-select and gizmo interactions for current set of mesh objects that support selection, by manipulating the active UGeometrySelectionManager.
ModelingMode now creates a UGeometrySelectionManager and UModelingSelectionInteraction on mode startup, if 'persistent selections' are enabled in the project settings. This replaces the previous persistent selection system/manager, which is no longer created/registered.
UModelingToolsEditorMode::ShouldDrawWidget() and ::ComputeBoundingBoxForViewportFocus() updated to support active Selection.
Functions ::OnToolsContextRender(), ::OnToolPostBuild(), ::GetGeometrySelectionChangesAllowed(), ::TestForEditorGizmoHit(), ::UpdateSelectionManagerOnEditorSelectionChange() added to support selection system.
FModelingToolsEditorModeToolkit will add buttons for selection control if Persistent Selections are enabled. Dynamic updates to Palette based on active selection are initiated by EdMode. Currently the selection-actions palette is empty.

GeometrySelection.h/cpp: FGeometrySelection, FGeometrySelectionEditor, representation and manipulation of a generic element-level selection, stored as a set of uint64. Editor makes changes to Selection while tracking deltas.
GeometrySelectionUtil.h/cpp: utility and helper functions for editing/processing a mesh+selection
GeometrySelector.h: FGeometryIdentifier type used to identify target objects with element-level selection support. IGeometrySelector interface that defines API for element selection for a type of target object. Factory type for spawing instances. IGeometrySelectionTransformer interface that defines API for element-level transformation
GeometrySelectionManager.h/cpp: UGeometrySelectionManager that maintains set of 'active targets' with associated Selector, Selection, and SelectionEditor, and provides high-level API for creating and querying element selections, 3D transforms of selections, selection undo/redo, and (currently) limited debug rendering
GeometrySelectionChanges.h/cpp: FChange types for element selection changes
DynamicMeshSelector.h/cpp: implementation of IGeometrySelector for UDynamicMesh/Component
