x86/cpuid: Enable CPUID Faulting for PV control domains by default
The domain builder no longer uses local CPUID instructions for policy
decisions. This resolves a key issue for PVH dom0's. However, as PV dom0's
have never had faulting enforced, leave a command line option to restore the
old behaviour.
Advertise virtualised faulting support to control domains unless the opt-out
has been used.
