Problem Summary: Single-rowset grouped compaction introduces rowsets whose segments are non-overlapping only within recorded groups. This pr support record the partial segments nonoverlap relation in `segment_group_sizes` in `RowsetMetaPB`(Each value is the number of consecutive output segments in one non-overlapping group.) and `NONOVERLAPPING_WITHIN_GROUP` in `SegmentsOverlapPB`. And in `VerticalBlockReader`, only read the first segment in the each group to reduce memory.
