Breaking change in type alias with bound

[robertbastian]

The formatting of the declaration

type W<'a> = T::W<'a> where T: 'a;

changed in nightly-2024-09-22. The above code is formatted on stable, now it gets formatted to

type W<'a>
    = T::W<'a>
where
    T: 'a;

This was an expected change. Previously rustfmt didn't format type aliases that had trailing where clauses and now it does based on the prescription in the style guide.
