NOTE
===
Refactor and optimize `SortRowStepUtil` to make it efficient and more
readable.
1. Firstly we get all the indices for the 3 groups: dictionary columns, non
dictionary dimension columns and measures;
2. Then for each group, just iterate the source row and copy data to each
group without any if-else branch.
