[7.x] Publish resources.stub in stub:publish command (#33862)

* [7.x] Add a new helper to determine the true parent of a class.

Some examples of use are:

```php
class_parent_initial(HasMany::class); // Returns Relation::class
class_parent_initial(HasOne::class); // Returns Relation::class
class_parent_initial(HasOneOrMany::class); // Returns Relation::class
```

* [7.x] Publish resources.stub in stub:publish command

* Remove parent_class helper

* Update stub resources to match the format of the other publishable stubs.
