OCPBUGS-61843: UPSTREAM: 131850: cpumanager: uncorecache alignment for odd integer cpus

[ffromani]

Cherry-pick of upstream 131850 to release 4.20

backport notice note the e2e portion of commit 366615b is intentionally stripped as it doesn't apply against 4.20. The reason for this is when 131850 merged upstream kubernetes#130274 was still underway.
