Split UnCoreCache Toplogy Awareness in CPU Manager

This KEP proposes to introduce a new CPU Manager static policy option, "prefer-align-cpus-by-uncorecache", that groups CPU resources by uncore cache where possible. An uncore cache, also known as the last-level-cache, refers to the cache that exists at a shared level among CPU cores, unlike low-level caches which are dedicated per individual core. The opt-in feature changes the CPU assignment algorithm to recognize and sort CPUs by uncore cache, and then allocate CPUs aligned to the fewest uncore caches as possible. This is primarily beneficial for CPU architectures that utilize multiple uncore caches, or split uncore caches, within the processor. In cases where the number of CPUs requested exceeds the number of CPUs grouped in a uncore cache, the algorithm attempts to align allocations at a best-effort policy to reduce assignments of CPUs across minimal uncore caches. If the CPU Manager cannot align optimally, it will still admit the workload as before. Uncore cache assignment will be preferred but not a strict requirement for this feature.
