[BUG] GROUPING func and ORDER BY are used at the same time to report …

…NullPointerException (#6266)

fix #6265

The reason for the error is that the `Grouping Func Exprs` is substituted twice. In the first substitution, `VirtualSlotRef` is used to replace the original `SlotRef`, and in the second substitution, `VirtualSlotRef` is reported in the `getTable()` Times Null pointer. IN
```
} else if (((SlotRef) child).getDesc().getParent().getTable().getType()
```
For the first substitution, the List of executable exprs in select clause has been substituted.
```
groupingInfo = new GroupingInfo(analyzer, groupByClause.getGroupingType());
            groupingInfo.substituteGroupingFn(resultExprs, analyzer);
```
In the second substitution, actually only need to substitute the unique expr in Ordering exprs.
```
createSortInfo(analyzer);
        if (sortInfo != null && CollectionUtils.isNotEmpty(sortInfo.getOrderingExprs())) {
            if (groupingInfo != null) {
                groupingInfo.substituteGroupingFn(sortInfo.getOrderingExprs(), analyzer);
            }
        }
```
change into:
```
createSortInfo(analyzer);
        if (sortInfo != null && CollectionUtils.isNotEmpty(sortInfo.getOrderingExprs())) {
            if (groupingInfo != null) {
                List<Expr> orderingExprNotInSelect = sortInfo.getOrderingExprs().stream()
                        .filter(item -> !resultExprs.contains(item)).collect(Collectors.toList());
                groupingInfo.substituteGroupingFn(orderingExprNotInSelect, analyzer);
            }
        }
```
