This PR optimizes cooperative assignment validation in ConsumerCoordinator. Avoid HashSet.removeAll(List) in ConsumerCoordinator.validateCooperativeAssignment because it may repeatedly call List.contains and degrade to `O(n^2)` time complexity. Use explicit HashSet removals to keep the added/revoked partition calculation linear in the number of old owned and newly assigned partitions.
