selftests: kvm: switch to using KVM_X86_*_VM
This removes the concept of "subtypes", instead letting the tests use proper
VM types that were recently added. While the sev_init_vm() and sev_es_init_vm()
are still able to operate with the legacy KVM_SEV_INIT and KVM_SEV_ES_INIT
ioctls, this is limited to VMs that are created manually with
vm_create_barebones().
