HV: add cpu affinity info for SOS VM

Browse Source 
Previously the CPU affinity of SOS VM is initialized at runtime during
sanitize_vm_config() stage, follow the policy that all physical CPUs
except ocuppied by Pre-launched VMs are all belong to SOS_VM. Now change
the process that SOS CPU affinity should be initialized at build time
and has the assumption that its validity is guarenteed before runtime.
