PR apache#34032 introduce a new method to get splits batch by batch, but it removed a logic that BE will merge scan ranges to avoid too many scan ranges being scheduled. This PR mainly changes: 1. Add scan range merging logic back. 2. Change the default file split size from 8MB to 64MB, to avoid too many small split.
