hv: sched: use get_running_vcpu to replace per_cpu vcpu with cpu sharing

Browse Source 
With cpu sharing enabled, per_cpu vcpu cannot work properly as we might
has multiple vcpus running on one pcpu.
Add a schedule API sched_get_current to get current thread_object on
specific pcpu, also add a vcpu API get_running_vcpu to get corresponding
vcpu of the thread_object.
