Class Contraint Validator on configuration using interfaces doesn't work

[sclorng]

Describe the bug

Following the work on #15081 class constraint are not called but contraint on properties does.

Expected behavior

Given

@ConfigMapping(prefix = "foo")
@CustomFalse
public interface TestConfig {
}

@Target({ TYPE, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { CustomFalseValidator.class })
@Documented
public @interface CustomFalse {
    String message() default "nothing you can do";

    Class<?>[] groups() default { };

    Class<? extends Payload>[] payload() default { };
}

public class CustomFalseValidator implements ConstraintValidator<CustomFalse , TestConfig> {

    @Override
    public boolean isValid(TestConfigconfig, ConstraintValidatorContext context) {
        return false;
    }
}

Validation should failed.

Actual behavior

Validation pass
