hv: use vcpu_affinity[] in vm_config to support vcpu assignment

Browse Source 
Add this vcpu_affinity[] for each VM to indicate the assignment policy.
With it, pcpu_bitmap is not needed, so remove it from vm_config.
Instead, vcpu_affinity is a must for each VM.

This patch also add some sanitize check of vcpu_affinity[]. Here are
some rules:
  1) only one bit can be set for each vcpu_affinity of vcpu.
  2) two vcpus in same VM cannot be set with same vcpu_affinity.
  3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM.

v4: config SDC with CONFIG_MAX_KATA_VM_NUM
v5: config SDC with CONFIG_MAX_PCPU_NUM
