We have qom-list-types, but it returns info for all QOM types,
not just device types.

I see two possible approaches for this:

* Decide that every QOM type (devices, backend objects,
  machine-types) will have this flag, and just add it to
  qom-list-types.
* Add device-list-types or query-device-type commands,
  specific for TYPE_DEVICE.

I'm not sure which one is better.  The latter is more
conservative and safer, but will require duplicating the same
work for machine-types and backend objects later.
