kata-deploy: register qemu-nvidia-cpu runtime classes

Make qemu-nvidia-cpu and qemu-nvidia-cpu-runtime-rs first-class kata-deploy
citizens: add them to the shim allow-lists and per-arch defaults in the
kata-deploy binary (amd64 + arm64), expose them as shims in the Helm
values and give them a RuntimeClass with a lightweight pod overhead
(320Mi/250m) - they carry no GPU, so the GPU 10Gi budget doesn't apply.
