Reimplement popular Mypy plugins

[johnthagen]

Description

In order to migrate from Mypy to Ruff for static type checking, one thing users may need are reimplementations of the most popular Mypy plugins.

• https://mypy.readthedocs.io/en/stable/extending_mypy.html#extending-mypy-using-plugins

Assuming for a moment that exposing a Mypy-compatible plugin interface is out of scope, the following Mypy plugins are ones I've seen in wide use within the community and could be considered:

• Some appear built into Mypy already: https://github.com/python/mypy/tree/master/mypy/plugins
• (Deprecated) Numpy: https://numpy.org/devdocs/reference/typing.html#mypy-plugin
• Pydantic: https://docs.pydantic.dev/latest/integrations/mypy/#enabling-the-plugin
• django-stubs: https://github.com/typeddjango/django-stubs?tab=readme-ov-file#installation
• djangorestframework-stubs: https://github.com/typeddjango/djangorestframework-stubs?tab=readme-ov-file#installation

Another list of Mypy plugins I found:

The numpy plugin is deprecated and the stubs are not plugins, right? Might want to remove those from your list.

django-stubs and djangorestframework-stubs both expose mypy plugin on top of the stubs
