Change the default behavior of partition pruning

Change the default behavior of partition pruning for Iceberg tables. #80583 (Melvyn Peignon).
Changed the default partition pruning behavior for Iceberg tables in ClickHouse.

Why it matters

This feature modifies how ClickHouse handles partition pruning when querying Iceberg tables. By changing the default behavior, it improves query efficiency and performance by better pruning unnecessary partitions, reducing data scanned and speeding up query execution.

How to use it

Users benefit from this enhancement automatically as it changes the default behavior. No additional configuration is required to enable the improved partition pruning for Iceberg tables.
