Provide copy constructors for SILOpenedArchetypesTracker.
Provide copy constructors for SILOpenedArchetypesTracker.

Provide proper copy constructors to ensure correctness. And forbid assignments between  SILOpenedArchetypesTracker objects.
Until now those copy constructors were automatically generated by the C++ compiler, but it was wrong, because two SILOpenedArchetypesTracker objects would sometimes share their internal representations, which resulted in a use-after-destruction bugs.
