Summary
part of #19622
Context: In the final aggregation stage, incoming data is already partitioned by the partial aggregation stage. As a result, when spilling occurs, all data falls into a single bucket.
Issue: Our design intended to halve memory usage during a spill, but a bug prevented this from happening.
Fix: This commit resolves the issue by adjusting the start bit, which correctly splits the data into two parts.
Testing: Verified by regression test test_partition_mask_with_start_bit.
