What problem does this PR solve?
Related PR: #48156
Problem Summary:
Previously, the same thread pool was used to calculate the DeleteBitmap during both the build rowset and publish stages. This led to high CPU usage and resource contention, especially impacting memtable flushing performance.
To mitigate this, a dedicated thread pool is introduced for DeleteBitmap computation during the build rowset stage. This new pool is configured with a lower maximum thread count (8 vs. the original 32) to better control resource consumption and reduce interference with other critical operations.
