cryptodev: Introduce cryptodev alg type in QAPI

Introduce cryptodev alg type in cryptodev.json, then apply this to
related codes, and drop 'enum CryptoDevBackendAlgType'.

There are two options:
1, { 'enum': 'QCryptodevBackendAlgType',
  'prefix': 'CRYPTODEV_BACKEND_ALG',
  'data': ['sym', 'asym']}
Then we can keep 'CRYPTODEV_BACKEND_ALG_SYM' and avoid lots of
changes.
2, changes in this patch(with prefix 'QCRYPTODEV_BACKEND_ALG').

To avoid breaking the rule of QAPI, use 2 here.
