This patch adds an --sve command line option to allow the Scalable Vector Extension to be enabled when creating a guest. This requires use of the new KVM_ARM_VCPU_FINALIZE ioctl before the vcpu is runnable, so a new hook kvm_cpu__configure_features() is added to provide an appropiate place to do this work. The kernel does not enable SVE by default, and for now kvmtool adopts the same policy: without --sve, SVE is not enabled for the guest even if the host supports it.
