Add `AnyLogger` type (`Logger | LoggerAdapter` alias)

Feature or enhancement

Proposal:

AnyLogger: TypeAlias = Logger | LoggerAdapter

According to the docs, LoggerAdapter should look mostly like Logger. So it would be really nice to have a type that can be used for both Logger and LoggerAdapter.

I would need it when I want to hold a logger instance, but I don't really care if it's Logger or LoggerAdapter.
So I want to support both options.

It may sound like an antipattern, according to the docs, but using LoggerAdapter is the recommended way of passing contextual info (according to the docs).

Even when using contextvars for holding the logger, a AnyLogger type would be handy indeed.

I am willing to submit a PR fixing this issue, like I tried to do before:
https://github.com/python/cpython/pull/126057

Has this already been discussed elsewhere?

从 logging 模块的 Logger 和 LoggerAdapter 入口开始，检查 issue 中展示的拟议 TypeAlias。查看之前的 pull request 以了解实现背景，然后确认所得类型涵盖两种 logger 形式，同时不改变其文档所述的行为。
