Change summary:
- Removed SSubobjectBlueprintEditor::FOnNewSubobjectAdded typedef and OnNewSubobjectAdded delegate members. Deprecation was not needed as these were added after the 5.0 release.
- Restored SSubobjectBlueprintEditor::AddNewSubobject() back to its original implementation (prior to adding the now-defunct OnNewSubobjectAdded event).
- Added USubobjectDataSubsystem::OnNewSubobjectAdded() to allow potential listeners to register for and receive successful subobject "add" event notifications.
- Modified USubobjectDataSubsystem::AddNewSubobject() to broadcast new subobject data to any registered listener(s) after a successful add.
- Added FBlueprintEditor::DeferredNamespaceImports to stack auto-imports for events that can be triggered more than once within a single frame.
- Modified FBlueprintEditor::OnComponentAddedToBlueprint() to handle subobject add events that target editor Blueprint objects. Also fixed to query the subobject class for its default import set instead of the subobject itself.
- Modified the FBlueprintEditor dtor to unregister the OnBlueprintUnloaded() event handler as I noticed this was not previously being done (benign as the shared ptr was skipped for being invalid, but this now removes us from the broadcast chain).
- Fixed up minor formatting inconsistencies in some legacy FBlueprintEditor analytics-related code paths.

Fix asserts as a result of replacing actor components without going through proper register/unregister lifecycle
Move logic for component class changing out of the details customization and in to the subobject data subsystem

This is needed because when the user drags a new scene component over the existing one, the old one should be deleted but is still marked as the SceneRoot (and cannot be deleted because we have to update the instances of the archetypes)

Correctly sort non-scene components to the bottom of the component tree.
This is some logic that was missed during the SCS editor refactor and is known to work already.

The SubobjectDataSubsystem is how users can manipulate a given object within Blueprints or Python scripting. Given a Uobject instance in a level or a UBlueprint asset, you can use GatherSubobjectData to get get an array of handles that you can use to manipulate that subobject.
This is what the new SubobjectEditor (Previously the SCS editor) will be using instead of having all its logic within slate code.
