[birt-dev] CheckIn: Support direct usage of row["__rownum"] as group key

["Lin Zhu" <lzhu@xxxxxxxxxxx>]

- Summary:
Support direct usage of row[“__rownum”] as group key.

- Bugzilla Bug (s) Resolved:
None

- Description:
In original implementation, “__rownum” cannot be recognized as default row index column name so that need to be bound before being used. This is however incorrect and user should be able to refer to row[“__rownum”] without binding it. This check-in fixes this problem.

- Tests Description:
Unit test.
