[PHPUnit12] Drop ConstraintValidatorTestCase from AllowMockObjectsWhereParentClassRector triggers

The Symfony fix in symfony/symfony#62745 (shipped in symfony/validator
6.4.31 / 7.3.9 / 7.4.3 / 8.0.3) removed the underlying need for the
attribute on this lineage. Rule now fires only on TypeTestCase.

Includes: code sample updated to TypeTestCase, orphaned enum constant
removed, existing fixture converted to TypeTestCase, stub added so the
converted fixture autoloads, and a transitive-inheritance skip fixture.

Closes rectorphp/rector#9650
