URL: https://github.com/apache/carbondata/pull/3955
### Why is this PR needed?
If a MV having aggregation, is created with all columns present in main
table, then some sub-queries are not hitting mv.
### What changes were proposed in this PR?
1. When all columns are given in projection in a aggregate query, logical
plan will not have Project node. Added Project node to logical plan in this
case, to match subqueries also to mv.
2. In GroupByGroupByNochildData pattern, added check for checking
CAST(aggregate expression) and used group by result to get final compensation
result
### Does this PR introduce any user interface change?
- No
### Is any new testcase added?
- Yes
