hv/config-tools: add the support for vCAT

Browse Source 
Add the VCAT_ENABLED element to RDTType so that user can enable/disable vCAT globally

Add the GUEST_FLAG_VCAT_ENABLED guest flag to enable/disable vCAT per-VM.

  Currently we have the following per-VM clos element in scenario file for RDT use:
    <clos>
      <vcpu_clos>0</vcpu_clos>
      <vcpu_clos>0</vcpu_clos>
    </clos>

  When the GUEST_FLAG_VCAT_ENABLED guest flag is not specified, clos is for RDT use,
  vcpu_clos is per-CPU and it configures each CPU in VMs to a desired CLOS ID.

  When the GUEST_FLAG_VCAT_ENABLED guest flag is specified, vCAT is enabled for this VM,
  clos is for vCAT use, vcpu_clos is not per-CPU anymore in this case, just a list of
  physical CLOSIDs (minimum 2) that are assigned to VMs for vCAT use. Each vcpu_clos
  will be mapped to a virtual CLOSID, the first vcpu_clos is mapped to virtual CLOSID
  0 and the second is mapped to virtual CLOSID 1, etc

Add xs:assert to prevent any problems with invalid configuration data for vCAT:

  If any GUEST_FLAG_VCAT_ENABLED guest flag is specified, both RDT_ENABLED and VCAT_ENABLED
  must be 'y'

  If VCAT_ENABLED is 'y', RDT_ENABLED must be 'y' and CDP_ENABLED must be 'n'

  For a vCAT VM, vcpu_clos cannot be set to CLOSID 0, CLOSID 0 is reserved to be used by hypervisor

  For a vCAT VM, number of clos/vcpu_clos elements must be greater than 1

  For a vCAT VM, each clos/vcpu_clos must be less than L2/L3 COS_MAX

  For a vCAT VM, its clos/vcpu_clos elements cannot contain duplicate values

  There should not be any CLOS IDs overlap between a vCAT VM and any other VMs
