When an unconstrained type or lifetime parameter is detected in an `impl`, provide more specific help based on its usage: - If the parameter is entirely unused, suggest removing it. - If it is used in the `impl` body but not the `Self` type, suggest including it in the `Self` type and the struct definition. This also adds a comprehensive UI test for these cases.
