`inspect.getmembers_static` triggers `__getattribute__`

Bug report

inspect.getmembers_static is documented as not triggering __getattribute__, but it can trigger it via dir. For example the following hits the recursion limit:

class A:
    def __getattribute__(self, name: str) -> Any:
        getmembers_static(self)
        return "all attrs exist!"

A().anything

(A workaround for examples like this one is to add the base cases required by dir to __getattribute__:

if name in ("__dict__", "__class__"):
    return object.__getattribute__(self, name)

(The __dict__ case is not always needed depending on the __dir__ implementation.))

Switching getmembers_static to use dir_static (gh-55979) would fix this problem, I believe. getmembers_static already documents that it can't find the dynamically created attributes, etc. that getattr_static can't find, so I don't think such a change would be breaking.

Your environment

• CPython versions tested on: 3.11.0
• Operating system and architecture: Linux-based, x86_64

從實作 inspect.getmembers_static 以及 gh-55979 中引用的 dir_static 工作開始。重現遞迴範例，然後驗證成員檢查不再透過 dir 觸發 getattribute；當已回報的行為獲得修正，且不變更關於動態建立屬性的文件化限制時，即視為完成。
