Local Classes should error the same as Inner Classes

Description of the feature request

There is currently an error message when trying to use an inner class in a mixin that is not also a @Mixin class itself. This does not show on method local classes though, even though the same restrictions apply (attempting to use such a class results in org.spongepowered.asm.mixin.transformer.throwables.IllegalClassLoadError: <localclass> is in a defined mixin package <mixin.package> owned by <mixin.config> and cannot be referenced directly )
