qapi/crypto: Rename QCryptoHashAlgorithm to *Algo, and drop prefix

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.
