NUMA Utilization-Aware Topology Manager Policy Options

Extend the Topology Manager with a numa-allocation-strategy policy option that controls NUMA node selection based on current allocation state. Valid values are none (default - preserves existing behavior), most-allocated (packing), and least-allocated (spreading). These new policy options build on the Topology Manager policy options framework introduced in KEP-3545: Improved multi-numa alignment in Topology Manager. Like prefer-closest-numa-nodes from KEP-3545, the new options modify the behavior of existing Topology Manager policies (best-effort, restricted, single-numa-node) without introducing new policies.
