Is it possible to implement support for this type of overload?

還沒有人認領這個 Issue。

### 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?

Type Checking

### Expected Behaviour


### Actual Behaviour


### Reproduction steps

```lua
---@class Position
---@field x number
---@field y number
---@field z number
Position = {};

---@param x number
---@param y number
---@return number
---@overload fun(self:Position, pos: Position): number
function Position:GetExactDist2dSq(x, y)
if type(x) == "table" then
return self:GetExactDist2dSq(x.x, x.y);
end
local dx = x - self.x;
local dy = y - self.y;
return dx*dx + dy*dy;
end

```

從 issue 中的 Lua 重現開始，比較螢幕截圖中顯示的預期型別檢查行為與實際型別檢查行為。追蹤 language server 對 GetExactDist2dSq 的多載處理；當數值引數形式和帶有 Position 引數的多載都能正確通過型別檢查時，即表示完成。
