morrySnow d88caca44a [fix](Nereids) push down topn distinct through join by mistake (#31396 )

should not push down topn distinct through join when the output
columns of the corresponding child of join is more than
aggregate distinct columns.

for example for LEFT_OUTER_JOIN:

left child of join's output is: c1, c2, c3.
distinct columns is: c1, c2
topn: limit 2

if we push down topn distinct, we could get result of join like this:

```
c1    c2    c3, ...
1     2     1
1     2     2
```

and the final result we get is:

```
c1    c2
1     2
```

this is wrong, because we need 2 lines, but only return 1.
