Description

Basically native Parameter and ReturnType do not handle overloaded interfaces.

Here is a workaround: https://github.com/microsoft/TypeScript/issues/14107#issuecomment-1146738780

Contributor guide

Research direction
Study the linked workaround for overloaded interfaces, understand how to extract parameters and return types using conditional types and inference, then implement OverloadParameters and OverloadReturnType types.
