Dont suggest `use<impl Trait>` when we have an edition-2024-related borrowck issue
#131186 implements some machinery to detect in borrowck when we may have RPIT overcaptures due to edition 2024, and suggests adding `+ use<'a, T>` to go back to the edition 2021 capture rules. However, we weren't filtering out cases when there are APITs in scope.
This PR implements a more sophisticated diagnostic where we will suggest turning any APITs in scope into type parameters, and applies this to both the borrowck error note, and to the `impl_trait_overcaptures` migration lint.
