YQL-21048: Support GROUPING SETS for YqlSelect
This patch unlocks a subset of `GROUPING SETS`, `ROLLUP` and `CUBE`
syntax for `YqlSelect`. The `sql` was easy, but I faced problems
at the `core` level. An existing expansion was OK, but type annotation
was changed to correctly annotate `GROUP BY` keys as `Optional`.
```haskell
notNullKeys groupBy =
union [
( intersection [ groupingSet | groupingSet in groupingSets ] )
| groupingSets in groupBy
]
```
It gives 60/100 (+9) TPC-DS queries.
