Add DynamicMeshSelector::UpdateAfterGeometryEdit API. StaticMeshSelector implementation updates static mesh after an Edit instead of emitting MeshChange on temporary DynamicMesh.
Delete and Retriangulate Commands now use this API instead of directly emitting transaction, so now these commands work properly on Static Meshes.
FStaticMeshComponentSelectorFactory::CanBuildForTarget now only allows UStaticMeshComponent specifically, filtering out subclasses. This is not ideal but I don't know what else we can do for now, there are many subclasses like ISMC, SplineMeshComponent, etc, that will not work w/ the Selection system. Also now filtering out Engine assets and cooked assets.
ModelingToolsEditorMode now listens for blueprint pre-compiles, and when this occurs, clears the active selection and selection targets. This is necessary because if the selection Component was part of a BP, on recompile it is re-instanced and the old pointer goes stale. Possibly can handle this better or at a more granular level, but clearing the selection is safest. This currently results in things not being undoable because the FChange transactions are on the "old" UDynamicMesh that no longer exists.
UModelingToolsEditorMode::UpdateSelectionManagerOnEditorSelectionChange now does a more thorough job of inspecting the current Actor/Component selection to find Components that could work w/ the selection system.

Add UInteractiveCommandResult, UInteractiveCommand::ExecuteCommand() now optionally can return a result subclass
Add UGeometrySelectionEditCommandResult, UGeometrySelectionEditCommand now can optionally return an "output" selection via this type
UGeometrySelectionManager::ExecuteSelectionCommand optionally can restore a selection after a command, via UGeometrySelectionEditCommandResult
Add UDisconnectGeometrySelectionCommand, implements disconnection of selected triangles (ie separates but not into a new mesh)
Add UModifyGeometrySelectionCommand, implements various selection edits (select all, expand to connected, invert, invert connected, expand, contract)
Add IGeometrySelector::InitializeSelectionFromPredicate() and ::UpdateSelectionFromSelection(), implement in UDynamicMeshSelector, used to implement selection edit commands
Add UI to enable new commands in Modeling Mode

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.
