hv: dynamically configure CPU affinity through hypercall

Browse Source 
- add a new member cpu_affinity to struct acrn_create_vm, so that acrn-dm
  is able to assign CPU affinity through HC_CREATE_VM hypercall.

- if vm_create.cpu_affinity is zero, hypervisor launches the VM with the
  statically configured CPU affinity.
