Current equalSansNullability only considers the atomic type, not support Array/MULTISET/Map(struct type can be supported by equalAsStructSansNullability).
This Jira mainly supports Array/MULTISET/Map type equal sans nullability
- equalSansNullability, handles atomic type
- equalAsCollectionSansNullability, handles type ARRAY/MULTISET
- equalAsMapSansNullability, handles type MAP
- equalAsStructSansNullability, handles type struct
