### Expected Behaviour

当一个类通过@overload定义了__call元方法。
当它的一个实例以__call的形式被调用，应该检测参数是否正确。
When a class defines a __call metamethod via @overload.
When one of its instances is called as __call, the argument should be checked to see if it is correct.

### Actual Behaviour

被正确地识别为了一个函数，但是没有检测其参数是否正确。
Is correctly identified as a function, but its arguments are not checked for correctness.

### Reproduction steps

```lua
---@class Callable
---@overload fun(tbl:table)
local Callable = {}
Callable.__index = Callable

---@return Callable
function Callable:extend()
return setmetatable({ __index = self, __call = self.__call }, self)
return

function Callable:__call(tbl)
for key, value in pairs(tbl) do
print(key)
end
end

-- other lua file
local instance = { }
instance.callable = Callable:extend()

instance:callable { a=1, b=2 } -- A warning should be thrown here because `instance` is passed in as the first argument (self).
instance.callable { a=1, b=2 } -- Correct call.
```

### Additional Notes
一个临时的解决方法：再次进行类型的声明。
Temporary workaround: Type declaration again.
```lua
local instance = { }
---@overload fun(tbl:table)
instance.callable = Callable:extend() --[[@as function]]

instance:callable { a=1, b=2 } -- A warning.
instance.callable { a=1, b=2 } -- Correct call.
```

我是在实现一个C#风格的Seter和Geter时发现的，我定义了一个Property类，子类会继承父类的Property。
为了使代码更加简洁，我定义了Property类的__call元方法，使得我可以以这样的风格进行声明：
I discovered this when implementing a C# style Seter and Geter, and I defined a Property class where subclasses inherit the Property of the parent class.
To make the code more concise, I define the __call metamethod of the Property class so that I can declare it in this style:
```lua
MyClass.property {
name = {
get = function(self)
return self._name
end,
set = function(self, value)
self._name = value
end,
}
}
```
### Log File

_No response_

从提供的 Lua 复现开始，检查语言服务器如何解析 __call 元方法上的 @overload，以及冒号调用与点号调用。完成标准是：冒号调用报告额外的 self 参数，而点号调用仍然有效，并覆盖这两种形式。
