[libvirt] [PATCH 3/5] query-command-line-options: query all the options in qemu-options.hx
vm_config_groups[] contain the options which have parameter, but some
legcy options haven't been added to vm_config_groups[].
All the options can be found in qemu-options.hx, this patch used two
new marcos to generate two tables, we can check if the option name is
valid and if the option has arguments.
This patch also try to visit all the options in option_names[], then
we won't lost the legacy options that weren't added to vm_config_groups[].
The options have no arguments will also be returned (eg: -enable-fips)
