Infer pcall arguments from the first function parameter

Hi 👋

I was wondering if it would be possible for LuaLS to infer the types of the arguments passed to pcall based on the signature of its first function argument. This would significantly improve developer experience, especially when working with typed Lua (e.g., EmmyLua annotations) or when relying on auto-completion and type checking.

Example:

local function greet(name: string)
  print("Hello, " .. name)
end

pcall(greet, "world") 
             ^- here we should see `name: string`

In this case, it would be great if LuaLS could infer that greet expects a string, and therefore type-check or suggest "world" accordingly when passed to pcall.

Currently, the parameters after the first one are not checked or suggested with much context, making it less ergonomic when using pcall (or other similar functions) for safe calls.

まず、例に示されている pcall の呼び出しを LuaLS がどのように処理し、関数シグネチャに対して引数をどのようにチェックしているかを追跡します。関連する型チェックと補完の経路を特定し、その後、最初の関数パラメーター以降の引数が、型付き Lua 呼び出しに期待されるコンテキストを受け取ることを確認します。
