qapi: Implement deprecated-input=reject for QMP command arguments
This policy rejects deprecated input, and thus permits "testing the
future". Implement it for QMP command arguments: reject commands with
deprecated ones. Example: when QEMU is run with -compat
deprecated-input=reject, then
{"execute": "eject", "arguments": {"device": "cd"}}
fails like this
{"error": {"class": "GenericError", "desc": "Deprecated parameter 'device' disabled by policy"}}
When the deprecated parameter is removed, the error will change to
{"error": {"class": "GenericError", "desc": "Parameter 'device' is unexpected"}}
