Memory pages in LazyMemorySegmentPool should be clear after they are released to MemoryManager

`LazyMemorySegmentPool` manages memory segments cache for join, agg, sort and etc. operators. These segments in the cache will be released to `MemoryManager` after some specify operations such as join operator finishes to build data in `LazyMemorySegmentPool.cleanCache` method. But these segments are still in `LazyMemorySegmentPool.cachePages`, it may cause memory fault if the `MemoryManager` has deallocated these segments
