Add types to parts of Django

Code of Conduct

• I agree to follow Django's Code of Conduct

Feature Description

I would like types and/or type hints to be added or allowed to be added to Django.

Problem

Right now when using Django it is not uncommon to need to look at the docs just to see what a function returns or what the arguments type is. While this has been proposed a few times now, the Python typing ecosystem has improved making this more viable. While there are some areas where this would be difficult and may even hurt the experience due to Django's complexity like the ORM. I feel that there are some parts like the request, response object, path, class-based views, etc that would greatly benefit from this.

Additional Details

This has been discussed before, most recently https://forum.djangoproject.com/t/revisiting-types-in-django-dep-14/37832.
I thought I would add it here as well.

This would also help solve many of the issues here https://groups.google.com/g/django-developers/c/at-G0hZrfXE.

We could split off the proposal to add Protocols for Resolvable and Compilable in the ORM as an "easy win" proposal ("🎉 ") since it's basically done.

We have moved this issue forward, so the next step here would be to setup a team around this idea and write a proposal on the path forward to accomplish this massive task
