For SQL `A last join (B last join C)`, it'll optimize and run `B last join C` lazily. Both batch mode and request(batch-request) mode are considered.
and also: - rm redundant code path in group_and_sort_optimized.cc

correct expr resolving in group_and_sort_optimized
Skip for the case `JOIN(TABLE, ...)`. Cluster optimize only happen with `JOIN(ROW, TABLE)`.
Do not optimize target table if resolved column is from different table, even column name does be the same.
