bind: annotate ObjC types with nullability annotations

This highly improves interop with Swift. It would map all
pointers as implicitly unwrapped optionals, which skip all
null safety checks. Adding `_Nullable` to pointer types
makes swift map them as optionals.

Also constructors are now nullable since it's valid to return nil from
Go code.
