- SmartObject gained knowledge whether it was registered as a part of a colleciton, or as a dynamic smart object.
- cleaned up SmartObjectComponents SOHandle setting an resetting - there's a separate function for invalidating the handle.
- added handling of SmartObjectComponent's destruction (as opposed to unregistration due to being streamed out, potentially temporarily)

In addition:
* SmartObjectCollection got deprecated and there's a auto-update path triggered in SmartObjectCollection::PostLoad
* SmartObjectComponent component can opt out of being a part of a collection with `bCanBePartOfCollection`
* Right now we limit SmartObjects to be registered with at most a single Collection. This might change in the future if required.
Note that this is the first change in a series, we're going to support miltiple collections per level with convenient ways of assigning SmartObjects to individual collections.
