Instead of requiring clients to actually call the query-cpu-*
commands to find out if they are implemented, remove them from
the output of "query-commands", so clients know they are not
available.
This is implemented by adding a new arch-specific hook:
arch_init_qmp_commands(), that can enable the available QMP
commands (which are now disabled by default).
