Support Non-Standard Default Types in ROLLUP, CUBE, and GROUPING SETS

Why it matters

This feature addresses the limitation where ROLLUP, CUBE, and GROUPING SETS did not handle data types that have non-standard default values correctly, enabling users to perform advanced grouping operations on a wider range of data types without default value conflicts.

How to use it

Users can now freely use columns with non-standard default values in ROLLUP, CUBE, and GROUPING SETS clauses in their SQL queries without additional configuration.
