Add support to sumneko's Lua extension

[matpratta]

Might require some extra fiddling with the .vscode directory, most specifically to set Lua version, ignore directory, library (for Codex) and max preloads (to support over 500kb of the Codex):

{
    "Lua.runtime.version": "Lua 5.3",
    "Lua.workspace.ignoreDir": [
        ".vscode",
        "out"
    ],
    "Lua.workspace.library": [
        "util/Codex.lua"
    ],
    "Lua.workspace.preloadFileSize": 1000,
    "Lua.workspace.maxPreload": 10000
}

The lua extension also does not pull type definitions from the new Codex.lua for library, system, unit, etc. The latest version of Codex.lua instantiates the class with "system = System()" . To get type definitions I either had to add the appropriate ---@type... annotations or revert them to references of the class "system = System" .

I'm not sure if this would impact anything using emmylua for annotations or just this extension's implementation.

@MatheusMK3 Be a bit careful with this. I've setup my own library paths so if the compiler starts modifying that, it might cause undesired effects.

@fiddlybits01 I might add the ---@type annotations to handle it, but the correct way of doing it is really system = System() as system is an instance of the System class here. The annotations shouldn't be an issue though.

As for @PerMalmberg's comment, I'm still considering what to do, I was considering detecting pre-existing configs and "extending" them, but I'm not 100% sure yet.
