Add command for reporting devices on Windows guest. The intent is not so
much to report the devices but more importantly the driver (and its
version) that is assigned to the device. This gives caller the
information whether VirtIO drivers are installed and/or whether
inadequate driver is used on a device (e.g. QXL device with base VGA
driver).

This could be neatly auto-generated for all qapi types. Not necessary
for now, but if you feel like doing it, that would be great.

Instead of the glist dance, you could use zero-terminater GArray of
char *, you will have to cast (GStrv)g_array_free(ids, FALSE), but
that's expected.
