Sergey Dyasli 6b85e42709 x86/sysctl: Implement XEN_SYSCTL_get_cpu_policy

Provide a SYSCTL for the toolstack to obtain complete system CPUID and MSR
policy information.

For the flask side of things, this subop is closely related to
{phys,cputopo,numa}info, so shares the physinfo access vector.

Extend the xen-cpuid utility to be able to dump the system policies.  An
example output is:

  Xen reports there are maximum 113 leaves and 3 MSRs
  Raw policy: 93 leaves, 3 MSRs
   CPUID:
    leaf     subleaf  -> eax      ebx      ecx      edx
