Add support for Symfony PasswordStrength Constraint

manual test.

Fatal error: Class Drupal\field_validation\Plugin\Validation\Constraint\PasswordStrengthConstraint cannot extend final class Symfony\Component\Validator\Constraints\PasswordStrength in E:\xampp\htdocs\drupal10\modules\field_validation\src\Plugin\Validation\Constraint\PasswordStrengthConstraint.php on line 16

Symfony\Component\Validator\Constraints\PasswordStrength is a final class, we could not extend it.

mark this as postponed.

I add a issue at github for symfony:
