Read/write property does not work with "allow_interpreted_subclasses"

Bug Report

Code generated by mypyc crashes at run-time when accessing a read/write property of an interpreted subclass.

To Reproduce

The mypyc code:

#entity.py
from mypy_extensions import mypyc_attr


@mypyc_attr(allow_interpreted_subclasses=True)
class EntityBase:

    def __init__(self) -> None:
        self._name = 'hello'

    @property
    def name(self) -> str:
        return self._name

    @name.setter
    def name(self, name: str):
        self._name = name


def print_name_property(entity: EntityBase):
    print(f'Property {type(entity)}: {entity.name}')

The driver code:

from reproducer import print_name_property, EntityBase


class EntitySubclass(EntityBase):

    def __init__(self):
        super().__init__()


def main():
    entity_subclass = EntitySubclass()

    print_name_property(entity_subclass)


if __name__ == '__main__':
    main()

Expected Behavior

The code should print 'hello' regardless if the attribute is accessed directly or via property.

Actual Behavior

Program crashes, when calling print_name_property(entity_subclass):

Traceback (most recent call last):
  File "/home/python/mypyc/reproducer.py", line 17, in <module>
    main()
  File "/home/python/mypyc/reproducer.py", line 13, in main
    print_name_property(entity_subclass)
  File "entity.py", line 20, in print_name_property
    print(f'Property {type(entity)}: {entity.name}')

AttributeError: 'EntitySubclass' object has no attribute '__mypyc_setter__name'

Process finished with exit code 1

Your Environment

• Mypy version used: 1.4.1
• Python version used: 3.11.0

Beginne mit der von mypyc generierten Behandlung von Properties in Klassen, die mit allow_interpreted_subclasses markiert sind, und verwende dabei den Reproduzierer EntityBase und EntitySubclass aus dem Issue. Führe das Beispiel mit der gemeldeten Umgebung aus und überprüfe, dass der Zugriff auf entity.name nicht mehr AttributeError auslöst und die erwartete hello-Ausgabe ausgibt.
