PS10, Line 845: Enables predicate subsetting for Iceberg plan nodes. If enabled, expressions
              :   // evaluated by Iceberg are not pushed down the scanner node.
Could you explain how this relates to Codegen optimization level? I could not find any comments here or on the associated Jira ticket about Iceberg predicate pushdown.
