Add a separate error for `dyn Trait` in `const fn`

Previously "trait bounds other than `Sized` on const fn parameters are unstable" error was used for both trait bounds (`<T: Trait>`) and trait objects (`dyn Trait`). This was pretty confusing.

This PR adds a separate error for trait objects: "trait objects in const fn are unstable". The error for trait bounds is otherwise intact.

This is follow up to #88907
