Summary

Similar request to #9022, which was resolved with #16149. But the fix only recognizes the following patterns:

SLF001 now recognizes the following as instance-like and will not report them:

• cls()/mcs()
• super().__new__()
• SameClass()/SameClass[int]()/Annotated[SameClass[int], ...]()
• a: SameClass/a: SameClass[int]/a: Annotated[SameClass[int], ...]

It would be great if any expression typed as Self could also be recognized.

Here's a link to an example: https://play.ruff.rs/915c7db2-e843-4f50-8861-8dd0f61e79a8

class Foo:
    def __init__(self, x: int) -> None:
        self._x = x

    def foo(self) -> None:
        this = self
        print(this._x) # Private member accessed: `_x` (SLF001)
        print(self._x)
