k8s: New Conversion from cgroup v1 CPU Shares to v2 CPU Weight

An improved, non-linear conversion from cgroup v1 CPU shares to cgroup v2 CPU weight replaces the previous linear formula to restore intended priority relationships and improve granularity for small CPU requests. The change is implemented in OCI runtimes (runc >=1.3.2, crun >=1.23) and may require updates to tooling that assumed the old mapping.
