diagnostics: `Box<dyn Trait>` suggestion with multiple matching impl

The two altered expectation messages both seem like improvements:

- `coerce-expect-unsized-ascribed.stderr` says you can go
  `Box<char> -> Box<dyn Debug>`, which you can.
- `upcast_soundness_bug.stderr` used to say that you could go
  `Box<dyn Trait<u8, u8>> -> Box<dyn Trait>`, which you can't,
  because the type parameters are missing in the destination
  and the only ones that work aren't what's needed.
