qapi: keep names in 'CpuInstanceProperties' in sync with struct CPUCore

struct CPUCore uses 'id' suffix in the property name. As docs for
query-hotpluggable-cpus state that the cpu core properties should be
passed back to device_add by management in case new members are added
and thus the names for the fields should be kept in sync.
