machine: replace query_hotpluggable_cpus() callback with has_hotpluggable_cpus flag

Browse Source 
Generic helper machine_query_hotpluggable_cpus() replaced
target specific query_hotpluggable_cpus() callbacks so
there is no need in it anymore. However inon NULL callback
value is used to detect/report hotpluggable cpus support,
therefore it can be removed completely.
Replace it with MachineClass.has_hotpluggable_cpus boolean
which is sufficient for the task.
