1. Change USE_PSA_CRYPTO_INIT/DONE to MD_OR_USE.
2. Add missing occurrences - some of these were already necessary in
principle (in one form or another) but where missing and this was not
detected so far as `psa_hash` doesn't complain in case of a missing
init, but now MD makes it visible.
3. Add missing include in ssl_test_lib.h.
