Features
   * Add missing PSA macros declared by PSA Crypto API 1.0.0:
     PSA_ALG_IS_SIGN_HASH, PSA_ALG_NONE, PSA_HASH_BLOCK_LENGTH, PSA_KEY_ID_NULL.

Bugfix
   * The existing predicate macro name PSA_ALG_IS_HASH_AND_SIGN is now reserved
     for algorithm values that fully encode the hashing step, as per the PSA
     Crypto API specification. This excludes PSA_ALG_RSA_PKCS1V15_SIGN_RAW and
     PSA_ALG_ECDSA_ANY. The new predicate macro PSA_ALG_IS_SIGN_HASH covers
     all algorithms that can be used with psa_{sign,verify}_hash(), including
     these two.
