The NormalizeRepeat rule can change the output of agg.
For example:
```sql
         SELECT
             col_int_undef_signed2 AS C1 ,
             col_int_undef_signed2
         FROM
             normalize_repeat_name_unchanged
         GROUP BY
         GROUPING SETS (
         (col_int_undef_signed2),
         (col_int_undef_signed2))
```
Before fixing the bug, the plan is:
```sql
LogicalResultSink[97] ( outputExprs=[C1#7, col_int_undef_signed2#1] )
      +--LogicalProject[94] ( distinct=false, projects=[C1#7, C1#7], excepts=[] )
         +--LogicalAggregate[93] ( groupByExpr=[C1#7, GROUPING_ID#8], outputExpr=[C1#7, GROUPING_ID#8], hasRepeat=true )
            +--LogicalRepeat ( groupingSets=[[C1#7], [C1#7]], outputExpressions=[C1#7, GROUPING_ID#8] )
               +--LogicalProject[91] ( distinct=false, projects=[col_int_undef_signed2#1 AS `C1`apache#7], excepts=[] )
                  +--LogicalOlapScan (  )
```
This can lead to column not found in LogicalResultSink, report error:
Input slot(s) not in childs output: col_int_undef_signed2#1 in plan:
LogicalResultSink[97] ( outputExprs=[C1#7, col_int_undef_signed2#1] )
child output is: [C1#7]

This pr makes agg output unchanged after normalized repeat. After
fixing, the plan is:
```sql
LogicalResultSink[97] ( outputExprs=[C1#7, col_int_undef_signed2#1] )
      +--LogicalProject[94] ( distinct=false, projects=[C1#7, C1#7 as `col_int_undef_signed2`apache#1], excepts=[] )
         +--LogicalAggregate[93] ( groupByExpr=[C1#7, GROUPING_ID#8], outputExpr=[C1#7, GROUPING_ID#8], hasRepeat=true )
            +--LogicalRepeat ( groupingSets=[[C1#7], [C1#7]], outputExpressions=[C1#7, GROUPING_ID#8] )
               +--LogicalProject[91] ( distinct=false, projects=[col_int_undef_signed2#1 AS `C1`apache#7], excepts=[] )
                  +--LogicalOlapScan (  )
```
