acrn-config: support generation of per vcpu clos configuraton

Browse Source 
Added "vcpu_clos" to configuration XML, here is an example of VM2 with 2 vCPUs:
  <clos desc="Class of Service for Cache Allocation Technology. Please refer SDM 17.19.2 for details and use with caution.">
	<vcpu_clos>1</vcpu_clos>
	<vcpu_clos>0</vcpu_clos>
  </clos>

A macro will be generated in vm_configuration.h:
  #define VM2_VCPU_CLOS          {1U, 0U}

And the macro will be used in vm_configuration.c:
  struct acrn_vm_config vm_configs[CONFIG_MAX_VM_NUM] = {
	...
	{
		...
		.clos = VM2_VCPU_CLOS,
		...
	}
  }
