Remove support for "@checked" annotations. Dart now has a "covariant" keyword that serves the same purpose. Fixes #28797 Note that this is a breaking change, not to the analyzer API but to the language semantics implemented by the analyzer; client code that wants the "@checked" behavior will now have to use the "covariant" keyword instead. Since the front end implementation of the type system only supports the "covariant" keyword, the impact on user code should be low; any user code that would be broken by this change is already broken under the front end. Google internal code has already been migrated to use "covariant".
