If the user provides a pre-allocated buffer for the hash result,
we must use that rather than re-allocating a new buffer.

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious. It's best used with
restraint.
QCryptoHashAlgorithm has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTO_HASH_ALG.
We could simply drop 'prefix', but then the prefix becomes
QCRYPTO_HASH_ALGORITHM, which is rather long.
We could additionally rename the type to QCryptoHashAlg, but I think
the abbreviation "alg" is less than clear.
Rename the type to QCryptoHashAlgo instead. The prefix becomes to
QCRYPTO_HASH_ALGO.
