Feature

Report where @deprecated symbols are used in the code.

Pitch

Python 3.12 is coming soon, and it introduces PEP 702 (the @deprecated decorator).mypy should support it.

(Technically PEP 702 will not be in Python 3.12, the PEP has not been accepted. But yes, mypy should support the draft standard and its use via typing_extensions)

If some people are interested, I wrote a small plugin to support this until it's part of mypy directly : https://github.com/Bendabir/mypypp

I don't really know the internals so it's probably a bit hacky but it appears to work.

If I'm correct, this issue is required for Python 3.13 support right? What's needed to move it forward?

Add basic support for PEP 702 (@deprecated). (#17476)
94c49a8 
Closes #16111

This PR provides only basic support. Many special cases might need
additional attention (descriptors, some special methods like `__int__`,
etc.). Other open issues are code comments, eventual documentation
updates, the deprecation message style, etc.). But I wanted to offer
these first steps before going on vacation (so I cannot respond to
possible reviews too soon).

Maybe someone wants to extend the list of (test) cases the basic support
should address?
