[Feature Request] Named Environment/Configuration Selection

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Libraries

Expected Behaviour

Not sure how best to word the title, but essentially, having different configuration names that the user can swap between would be nice. This is probably a really unlikely needed thing, but it's something I would need for my meta information.

Actual Behaviour

You can't specify some kind of named configuration.

Additional Notes

If you see https://github.com/LuaLS/lua-language-server/discussions/1834, I want to be able to differentiate between when certain functions exist/overload. The problem is that I can't really do that as-is, that I can tell at least. One thing I tried to look into were the configuration file details, but there's not a lot of documentation.

Ideally, I would be able to let the user specify how one of my variables is defined, e.g. love._console_name in my case would be 3DS, Switch or Wii U. I could then do something like so:

---@meta

---
---Provides access to information about the user's system.
---
---
---[Open in Browser](https://love2d.org/wiki/love.system)
---
---@class love.system
love.system = {}

if love._console_name == "3DS" then
	local play_coins = 0
	---Set the Play Coin count. \
	---This function is **ONLY** available on _Nintendo 3DS_.
	---@param coins integer
	function love.system.setPlayCoins(coins)
	    play_coins = coins
	end
	
	---Get the Play Coin count. \
	---This function is **ONLY** available on _Nintendo 3DS_.
	---@return integer current_coins
	function love.system.getPlayCoins()
	    return play_coins
	end
end

return love.system

and it would only show these as defined when on a "3DS" configuration.

The C++ Visual Studio Code extension has something similar:

Non è indicato alcun file di implementazione né alcun test. Inizia esaminando la documentazione sulla configurazione e la discussione 1834 per capire come le definizioni condizionali potrebbero essere selezionate da una configurazione denominata; il lavoro sarebbe completato quando gli utenti potessero cambiare configurazione e vedere solo le definizioni corrispondenti.
