`@overload` does not cooperate with `@class` when adding overloads to an inherited class method

调研方向
从复现中展示的 Lua 注解和补全行为开始，重点关注 @class 继承和 @overload 声明的处理方式。在 NeoVim 中复现该情况，并验证补全和悬停提示都显示继承的 "bar" 重载和子类的 "baz" 重载，且不存在参数类型不匹配。

Expected Behaviour
Adding an overload to a function inherited from another class should result in both the parent class' overloads and the new overload being suggested as autocomplete and hover tooltip entries.
Actual Behaviour
Adding an overload to a function inherited from another class makes that overload the only one that is recognized for the current class.
Reproduction steps
---@meta
---@class ParentClass
ParentClass = {}
---@param arg string
---@return unknown
---@overload fun(self, arg: "bar"): boolean
function ParentClass:foo(arg) end
---@class ChildClass : ParentClass
---@field foo fun(self, arg: "baz"): number
ChildClass = {}
ChildClass:foo(--[[Should suggest both "bar" and "baz", but only suggests "baz" and "bar" raises a param-type-mismatch]])
Redefining the function and adding an @overload there yields the same result.
Additional Notes
Having some way to mark a function redefinition as an overload (with strict checking that it does exist in the class defined as inherited from) would probably help solve this issue.
