lib/crypto: sha3: Support arch overrides of one-shot digest functions

Add support for architecture-specific overrides of sha3_224(),
sha3_256(), sha3_384(), and sha3_512().  This will be used to implement
these functions more efficiently on s390 than is possible via the usual
init + update + final flow.
