When delete records are large, search pk one by one will result into
many `Pincells` call which creates lots of futures.
This patch make search pk execute in batch to reduce this cost.
Also add `GetAllChunks` API to utilize `PinAllCells` to reduce pins.

This patch create new channel for each `get_cells` invocation in case of

1. Use blocking memory allocation to wait until memory becomes available
2. Perform memory allocation at the file level instead of per task
3. Limit Parquet file reader batch size to prevent excessive memory
consumption

Enhance the partial result evaluation mechanism in delegator to use row
count based data ratio instead of simple segment count ratio for better
accuracy.
Key improvements:
- Introduce PartialResultEvaluator interface for flexible evaluation
strategy
- Implement NewRowCountBasedEvaluator using sealed segment row count
data
- Replace segment count based ratio with row count based data ratio
calculation
- Update PinReadableSegments to return sealedRowCount information
- Modify executeSubTasks to use configurable evaluator for partial
result decisions
- Add comprehensive unit tests for the new row count based evaluation
logic
This change provides more accurate partial result evaluation by
considering the actual data volume rather than just segment quantity,
leading to better query performance and consistency when some segments
are unavailable.

We’ve frequently observed data loss caused by broken mutual exclusion in
compaction tasks. This PR introduces a post-check: before modifying
metadata upon compaction task completion, it verifies the state of the
input segments. If any input segment has been dropped, the compaction
task will be marked as failed.
