This CL makes a number of small changes to dyn compatibility errors: - "object safety" has been renamed to "dyn-compatibility" throughout - "Convert to enum" suggestions are no longer generated when there exists a type-generic impl of the trait or an impl for `dyn OtherTrait` - Several error messages are reorganized for user readability Additionally, the dyn compatibility error creation code has been split out into functions. cc #132713 cc #133267
