Auto merge of #75608 - estebank:suggest-boxed-match-exprs, r=lcnr,varkor
More structured suggestions for boxed trait objects instead of impl Trait on non-coerceable tail expressions When encountering a `match` or `if` as a tail expression where the different arms do not have the same type *and* the return type of that `fn` is an `impl Trait`, check whether those arms can implement `Trait` and if so, suggest using boxed trait objects. Use structured suggestion for `impl T` to `Box<dyn T>`. Fix https://github.com/rust-lang/rust/issues/69107
