[vm] Get script of closure from owner as parent function may contain wrong script

When a mixin class is created, there might be anonymous closures copied over to the other script.
Previously the script of closure function is the script of its parent function, which is not true in that case.
The solution is to create a patch class as the owner if parent function has a different script object. Return script of owner when query for script of closure function.
