qapi/crypto: Rename QCryptoRSAPaddingAlgorithm 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.

QCryptoRSAPaddingAlgorithm has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTO_RSA_PADDING_ALG.

We could simply drop 'prefix', but then the prefix becomes
QCRYPTO_RSA_PADDING_ALGORITHM, which is rather long.

We could additionally rename the type to QCryptoRSAPaddingAlg, but I
think the abbreviation "alg" is less than clear.

Rename the type to QCryptoRSAPaddingAlgo instead.  The prefix becomes
QCRYPTO_RSA_PADDING_ALGO.
