qga: conditionalize schema for commands unsupported on non-Linux POSIX
Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on non-Linux POSIX
platforms
The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from
{"class": "CommandNotFound", "desc": "Command FOO has been disabled"}
to
{"class": "CommandNotFound", "desc": "The command FOO has not been found"}
This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.
