Nilstrieb 6f662176e7 Add migration lint for 2024 prelude additions
This adds the migration lint for the newly ambiguous methods `poll` and
`into_future`. When these methods are used on types implementing the
respective traits, it will be ambiguous in the future, which can lead to
hard errors or behavior changes depending on the exact circumstances.
