[SYSTEMDS-3850] Pipeline pruning after top-K cleaning
This patch introduces a pruning technique on the cleaning pipeline
returned by the top-K cleaning. We identify a smaller yet equally
effective subset of primitives for all top-performing pipelines,
which optimizes their scoring performance.
Closes #2251
