…en reading Parquet scalar columns. (apache#59833) Related PR: apache#58785 Problem Summary: The performance rollback was introduced in apache#58785. The reason is that, prior to apache#58785, reading ordinary columns did not require filling and saving the RL DL. apache#58785 combined the logic for reading ordinary columns from a struct with the logic for reading ordinary columns, and filled and saved the RL DL to populate the null map information of the struct. This PR re-separates the reading logic.
