Jamie Dale 00c1da79ba Removed selection annotations ...

These existed as an optimization for USelection to quickly know if an object was selected, without having to test its array. UTypedElementList has that optimization embedded, so at this point the selection annotations are just extra state to keep in-sync, and failure to do so has already lead to bugs.

This change removes them in the simplest way possible, by using a function pointer to callback into editor code from core/engine code (as core/engine cannot directly access the global selection state), though longer-term we probably want to remove IsSelected/IsSelectedInEditor from UObject and let specific systems provide that functionality if they need it (eg, AActor/UActorComponent could provide it by getting the selection set from the owner world, rather than the global state).
