target/s390x: report deprecated-props in cpu-model-expansion reply

Retain a list of deprecated features disjoint from any particular
CPU model. A query-cpu-model-expansion reply will now provide a list of
properties (i.e. features) that are flagged as deprecated. Example:

    {
      "return": {
        "model": {
          "name": "z14.2-base",
          "deprecated-props": [
            "bpb",
            "csske"
          ],
          "props": {
            "pfmfi": false,
            "exrl": true,
            ...a lot more props...
            "skey": false,
            "vxpdeh2": false
          }
        }
      }
    }

It is recommended that s390 guests operate with these features
explicitly disabled to ensure compatibility with future hardware.
