Add qemu-nvidia-cpu and qemu-nvidia-cpu-runtime-rs to the shared hypervisor
allow-lists and to the docker, nerdctl and free-runner k8s matrices, so the
CPU-only NVIDIA classes get the same smoke coverage as the other qemu
variants on x86_64.
Add run-k8s-tests-on-nvidia-cpu-arm64.yaml and wire it into ci.yaml: it
runs the k8s test suite for qemu-nvidia-cpu and qemu-nvidia-cpu-runtime-rs
on real arm64 (GH200) hardware, giving the CPU-only classes aarch64
coverage without disturbing the existing GPU arm64 CI.
The NVIDIA NUMA bats and the nv-test allow-list learn about the CPU-only
classes too, so they can be run by hand on a multi-node host, but the arm64
CI deliberately runs only the standard k8s suite: the GH200 it uses exposes
a single CPU-bearing NUMA node, so the multi-NUMA tests would merely skip.
While here, add an is_verity_enabled_runtime_class helper (the CPU-only
classes boot the verity-backed nvidia base image without being
confidential) and an is_nvidia_hypervisor helper, and use them in
k8s-measured-rootfs.bats and the kata-deploy Helm arch wiring.
