Allow wparam and lparam in similar_names

`wparam` and `lparam` are often used as generic parameter names in win32 (for example [WindowProc](https://docs.microsoft.com/en-us/previous-versions/windows/desktop/legacy/ms633573(v=vs.85))). This PR adds them to the similar_names exception list.

changelog: [`similar_names`] don't treat wparam and lparam as similar
