core/cpu: make cpu idle states simpler
Rework the CPU idle state code:
* in_idle is true for any kind of idle including spinning. This is not
used anywhere except for state assertions for now.
* in_sleep is true for idle that requires an IPI to wake up.
* in_job_sleep is true for in_sleep idle which is also cpu_wake_on_job.
