Issue description

        virtual Ref<Script> get_script() const override {
                if (native_info->get_script_func) {
                        GDExtensionObjectPtr script = native_info->get_script_func(instance);
                        return Ref<Script>(reinterpret_cast<Script *>(script));
                }
                return Ref<Script>();

Is not creating a functional reference.

GDExtensionObjectPtr is a part of gdextension_interface and is a void pointer to pas data pointers between GDExtesion and Godot Core.

In the images below you are able to see that the extension reinterpret_cast works fine.
And that the pointer is passed to core.
However at core Ref<Script> script_test stays a NULL value

I was hoping this would be solved by solving cpp 1119

Steps to reproduce

Create a custom script instance and create it using internal::gdextension_interface_script_instance_create and a GDExtensionScriptInstanceInfo that only implements get_property_list_func and get_script_func.

Minimal reproduction project

Difficult to create a minimal project.
Mostly looking for advice on what to test to find the actual source problem

I hope it is fixed with both of above need to fix several regressions during testing before I'm sure this issue is caused by the bug
