hv: sched: decouple idle stuff from schedule module

Browse Source 
Let init thread end with run_idle_thread(), then idle thread take over and
start to do scheduling.
Change enter_guest_mode() to init_guest_mode() as run_idle_thread() is removed
out of it. Also add run_thread() in schedule module to run
thread_object's thread loop directly.

rename: switch_to_idle -> run_idle_thread
