SCI: Stop making copies of ObjMap and remove related dead code
ObjMap owns Objects, so every time this map gets copied instead of referenced, it creates a copy of every single object in the associated script. This is expensive, and it breaks things like the `Object::syncBaseObject` call in savegame.cpp, which hasn't actually been doing anything since 58190c36b4cc84b3200239211d91b0291301db56 because it has been operating on copies.
