Enable SVE in the KVM guest when the 'max' cpu type is configured and KVM supports it. KVM SVE requires use of the new finalize vcpu ioctl, so we add that now too. For starters SVE can only be turned on or off, getting all vector lengths the host CPU supports when on. We'll add the other SVE CPU properties in later patches.
