[SPARK-12740] [SPARK-13932] support grouping()/grouping_id() in having/order clause
## What changes were proposed in this pull request?
This PR brings the support of using grouping()/grouping_id() in HAVING/ORDER BY clause.
The resolved grouping()/grouping_id() will be replaced by unresolved "spark_gropuing_id" virtual attribute, then resolved by ResolveMissingAttribute.
This PR also fix the HAVING clause that access a grouping column that is not presented in SELECT clause, for example:
```sql
select count(1) from (select 1 as a) t group by a having a > 0
```
## How was this patch tested?
Add new tests.
