Shenandoah: Should only clear CLD::_claim_strong mark for strong CLD iterations

    Description

      JDK-8273559 started to use CLD::_claim_other for heap iteration and for other iterations, except verfier, Shenandoah uses CLD::_claim_strong, but for those iterations, it clears all marks, instead of CLD::_claim_strong mark.

      I don't think it is a fatal bug, it just means heap iteration may walk a CLD by multiple workers.
