[`arithmetic_side_effect`]: allow different types on the right hand side for `Wrapping<T>`

Fixes rust-lang#11145

This lint has a list of allowed types, one of which is `Wrapping<T>`, but it was only actually allowed if the type on the right hand side was also `Wrapping<T>`, which meant that, for example, `Wrapping<u32> += u32` would still lint. It now allows binary ops involving `Wrapping<T>` regardless of the type on the rhs.
These impls have only existed since Rust 1.60.0, so that is probably why the lint was previously not handling this correctly

changelog: [`arithmetic_side_effect`]: allow different types on the right hand side for `Wrapping<T>` (e.g. `Wrapping<T> += T`)
