Extend allowed dunder methods (PLW3201)

Opened as a followup to discussion at #9706.

Kudos to @AlexWaygood for scraping all dunders from CPython:

> Most of them seem to be definitions in tests, internal implementation details that are undocumented, and/or leftovers from Python 2 that still haven't been cleaned up. The `__rich_*__` ones are because I have `rich` installed in a venv inside my cpython local clone, I think?

In my opinion, it would be useful to add `__wrapped__` , `__isabstractmethod__` and `__signature__` to the list in case one wants to define those as properties (it's a niche use case though), especially since `__class__` is in the list.
`__rich_*__` should definitely be supported, a lot of critical tools & libraries have integrations with rich (including pip or Pydantic).

Some external libraries also implement their own dunders, such as pyarrow's [`__arrow_array__` used in pandas](https://github.com/pandas-dev/pandas/blob/9b95e4596c5d47b5dcc3cbedf143023475930595/pandas/core/arrays/string_.py#L429) or [`__attrs_post_init__` from attrs](https://www.attrs.org/en/stable/init.html#post-init) (among others) which I can see being supported now.
How should we research and collect them? What criteria should we have?

Start with the PLW3201 implementation and the discussion referenced in #9706, then review the listed CPython, Rich, pyarrow, pandas, and attrs dunders. Define evidence-based criteria for supporting names such as __wrapped__, __rich_*__, __arrow_array__, and __attrs_post_init__, and document which additions the rule should accept.
