KVM: s390: selftests: Add regression tests for KMCTR, KMF, KMO and PCC crypto subfunctions

Extend the existing regression test framework for s390x CPU subfunctions
to include tests for the KMCTR (Cipher Message with Counter) KMO
(Cipher Message with Output Feedback), KMF (Cipher Message with Cipher
Feedback) and PCC (Perform Cryptographic Computation) crypto functions.

The test procedure follows the established pattern.
