 `__file__` is an optional attribute of modules, and it either is
 added/modified by magic logic like Nuitka, PyInstaller, cx_Freeze, and
 each new freezer needs to add per-package hacks to get Django working, and
 need to be fixed whenever Django internals change, or isnt provided by
 freezers like PyOxidizer which refuse to play that cat & mouse game (c.f.
 https://github.com/indygreg/PyOxidizer/issues/69).

 The solution is to use `importlib.resources` where-ever the code is
 accessing data files inside the Django package, or other modules.

 e.g. under PyOxidizer:
 ```
   File "django.test", line 3, in <module>
   File "django.test.client", line 14, in <module>
   File "django.core.handlers.base", line 8, in <module>
   File "django.urls", line 1, in <module>
   File "django.urls.base", line 8, in <module>
   File "django.urls.exceptions", line 1, in <module>
   File "django.http", line 5, in <module>
   File "django.http.response", line 15, in <module>
   File "django.core.serializers", line 23, in <module>
   File "django.core.serializers.base", line 7, in <module>
   File "django.db.models", line 3, in <module>
   File "django.db.models.aggregates", line 5, in <module>
   File "django.db.models.expressions", line 8, in <module>
   File "django.db.models.fields", line 11, in <module>
   File "django.forms", line 6, in <module>
   File "django.forms.boundfield", line 4, in <module>
   File "django.forms.widgets", line 26, in <module>
   File "django.forms.renderers", line 16, in <module>
 NameError: name '__file__' is not defined
 ```

 To make this feature contained, I would limit it to runtime code of
 Django, and exclude instances of `__file__` in docs and templates deployed
 into new projects which need to be "manage.py-relative-paths", such as
 those in https://github.com/django/django/pull/12005
