Support registering url routes via @decorator. (Locality of Behaviour)

### Code of Conduct

- [x] I agree to follow Django's Code of Conduct

### Feature Description

Support registering url routes via @decorator.

```python
@view(paths="foo/", name="foo")
def foo(request: HttpRequest) -> HttpResponse:
return HttpResponse("foo")
```

This blog post describes it better than I can: https://valberg.dk/bringing-locality-of-behaviour-to-django-views-and-urls.html

Forum post discussion here: https://forum.djangoproject.com/t/bringing-locality-of-behaviour-to-django-views-and-urls/21765

### Problem

New Django projects can be complicated and have lots of files, with code split between `views.py` and `urls.py`. It would be nice for beginners and simple projects to avoid needing a `urls.py` file and do all url registering in the `views.py` file itself.

Some people also consider this approach to be more DRY (don't repeat yourself).

### Request or proposal

### Additional Details

It shouldn't be the main recommended approach, as there are clearly disadvantages discussed in the forum post. But rather this should be an alternative option for for those who prefer this style.

Flask, FastAPI, and Django Ninja all use this approach, so it would be nice to have this method available for those who are more comfortable working with that style.

I think it could also allow for a less "heavyweight" project style by not needing a separate `urls.py`.

### Implementation Suggestions

The "Behind the scenes" section of the blog post has some implementation details. https://valberg.dk/bringing-locality-of-behaviour-to-django-views-and-urls.html#behind-the-scenes

Read the issue's blog post, especially its “Behind the scenes” section, and review the forum discussion for the proposed trade-offs. Compare the current separation between views.py and urls.py with the requested @view(paths="foo/", name="foo") style. Done means Django supports an optional decorator-based route registration approach without making it the main recommended style.
