Create composite index on segmentby columns
Previously we created one index per segmentby column, of the form `(col, _ts_meta_sequence_num)`. Compressed data is ordered by segmentby, then by orderby within the segments and lastly by the sequence number of the batch. So if segmentby columns are missing from the index, that index cannot be used to produce ordered output, requiring an extra sort step. A composite index containing all segmentby columns removes the additional sort step and gives better plans. Fixes #4314
