kmod-6.12-nvidia-r570: Add grid-license-check

Add a unit that checks for the license to be valid for GRID. Kubelet
requires this unit so if the license is not present, then the node never
joins the cluster. This prevents a situation where a node could fail to
get a license, join the cluster, and then later have workloads start to
fail due to the unlicensed status.
