cryptodev: Introduce 'query-cryptodev' QMP command

Browse source 
Now we have a QMP command to query crypto devices:
virsh qemu-monitor-command vm '{"execute": "query-cryptodev"}' | jq
{
  "return": [
    {
      "service": [
        "akcipher",
        "mac",
        "hash",
        "cipher"
      ],
      "id": "cryptodev1",
      "client": [
        {
          "queue": 0,
          "type": "builtin"
        }
      ]
    },
    {
      "service": [
        "akcipher"
      ],
      "id": "cryptodev0",
      "client": [
        {
          "queue": 0,
          "type": "lkcf"
        }
      ]
    }
  ],
  "id": "libvirt-417"
}
