Enhancement ---@fieldread, ---@fieldwrite or attribute modifiers on typing

還沒有人認領這個 Issue。

When using some c api's (In my case Factorio's modding api) when you retrieve a value you get one type, but you can set it with multiple different types.

```lua
---@class Surface
---@class Player
local Player = {}
---@fieldread surface Surface
---@fieldwrite surface Surface|string

local p = Player.surface --- p is Surface
p.surface = "Other Surface" --No warnings
```

Another thought I had was attribute types, which would more easily support more attributes in the future
```lua
---@field{read} surface Surface
---@field{write} surface Surface|string
---@field{read,write} surface -- the default if no attributes are supplied
```

該 issue 沒有指定檔案、測試或進入點。首先定位 language server 對 Lua 欄位註解和型別檢查的處理，然後將提議的 @fieldread/@fieldwrite 語法和屬性語法與現有的註解行為進行比較。完成的標準是確定一種支援獨立讀取型別和寫入型別的語法，並產生預期的警告行為。
