tests: cpu-plug-test: fix device_add for pc/q35 machines
Commit bc1fb850a3 silently broke device_add test for CPU hotplug which
resulted in test successfully passing though it wasn't actually run.
Fix it by making sure that all non present CPUs reported
by "query-hotpluggable-cpus" are hotplugged instead of making up
and hardcoding values.
Use of query-hotpluggable-cpus also allows consolidatiate device_add
cpu testcases and reuse the same test function for all targets.
While at it also add a check that at least one CPU was hotplugged,
to avoid silent breakage in the future.
Fixes: bc1fb850a3 (vl.c deprecate incorrect CPUs topology)
