[Feature request] Class-based auto-require

首先检查 language server 现有的 auto-require 设置以及相关的 #3201 请求。当基于类的建议能够生成所请求的 import 风格语句，而不是仅依赖文件名时，这项工作就完成了。

My project has some strict styling, and what we have is a system where:

• MyClass is the sole returned class in myclass.lua, annotated and everything
• Usage is local MyClass = import("src.myclass")

The language server has a setting for auto-requires. Unfortunately, it hardcodes the require function & is completely filename based.

I've just opened #3201 to add the import thing, but I'd like to request a setting which makes auto-requires work better with the class names, rather than being filename-based.

Ex. MyClass.something() suggests to require the file as local MyClass = import("src.myclass") rather than myclass.

We've considered either not caring (very ugly for code-style), manually fixing it every time (makes auto-requires kind of useless) or changing the filenames to be cased the same as the class (not a proper solution but a workaround -- one that would make the file structure look worse & fear for case sensitive filesystems)

As far as I can tell, this seems like a language server limitation rather than a design limitation. I would try to contribute this option myself, but this codebase seems too complicated for me to understand unfortunately...

(I just realized I opened a similar request a year ago -- I completely forgot and have closed it now.)
