hv: sched: Add sched_params struct for thread parameters

Browse Source 
Abstract out schedulers config data for vCPU threads and other hypervisor
threads to sched_params structure. And it's used to initialize per
thread scheduler private data. The sched_params for vCPU threads come
from vm_config generated by config tools while other hypervisor threads
need give them explicitly.
