target/arm/kvm64: max cpu: Enable SVE when available
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.
