Fix cls.__module__ value in extension script

[huchenlei]

Description

Minimal reproduction: Mikubill/sd-webui-controlnet#2753

Adding following file to the extension script/ folder will cause A1111 report script loading error

from __future__ import annotations
from dataclasses import dataclass


@dataclass
class PreprocessorParameter:
    label: str

Error log:

*** Error loading script: repro.py
    Traceback (most recent call last):
      File "D:\stable-diffusion-webui\modules\scripts.py", line 508, in load_scripts
        script_module = script_loading.load_module(scriptfile.path)

        class PreprocessorParameter:

        return wrap(cls)
      File "C:\Program Files\Python310\lib\dataclasses.py", line 1176, in wrap
        return _process_class(cls, init, repr, eq, order, unsafe_hash,
      File "C:\Program Files\Python310\lib\dataclasses.py", line 945, in _process_class
        and _is_type(type, cls, dataclasses, dataclasses.KW_ONLY,
      File "C:\Program Files\Python310\lib\dataclasses.py", line 712, in _is_type
        ns = sys.modules.get(cls.__module__).__dict__
    AttributeError: 'NoneType' object has no attribute '__dict__'

The root issue is that cls.__module__ is assigned to be file name in script_loading.py::load_module. This PR fixes the cls.__module__ so that dataclass along with __future__.annotations can be used together.
