morrySnow 1dccfa3d84 [enhancement](nereids) make SSB works (#10659)
enhancement
- refactor compute output expression on root fragment in nereids planner
- refactor aggregate plan translator
- refactor aggregate disassemble rule
- slightly refactor sort plan translator
- add exchange node on the top of plan node tree if it is needed
- slightly refactor PhysicalPlanTranslator#translatePlan

fix
- slotDescriptor should not reuse between TupleDescriptors
- expression's nullable now works fine
- remove quotes when parse string literal
- set resolvedTupleExprs in SortNode to control output
- remove the extra column in sortTupleSlotExprs in SortInfo

known issues
- aggregate function must be the top expression in output expression (need project in ExecNode in BE)
- first phase aggregate could not convert to stream mode.
- OlapScanNode do not set data partition
- Sort could not process expression like 'order by a + 1' and SortInfo generated in a trick way and should be refactor when we want to support 'order by a + 1'
- column prune do not work as expected
