qapi: Implement deprecated-output=hide for QMP command results
This policy suppresses deprecated bits in output, and thus permits
"testing the future". Implement it for QMP command results. Example:
when QEMU is run with -compat deprecated-output=hide, then
{"execute": "query-cpus-fast"}
yields
{"return": [{"thread-id": 9805, "props": {"core-id": 0, "thread-id": 0, "socket-id": 0}, "qom-path": "/machine/unattached/device[0]", "cpu-index": 0, "target": "x86_64"}]}
instead of
{"return": [{"arch": "x86", "thread-id": 22436, "props": {"core-id": 0, "thread-id": 0, "socket-id": 0}, "qom-path": "/machine/unattached/device[0]", "cpu-index": 0, "target": "x86_64"}]}
Note the suppression of deprecated member "arch".
