Support JSON type and subcolumns reading

Why it matters

This feature addresses the limitation where JSON type columns and their subcolumns could not be read from views. It enables users to seamlessly query JSON data through views, enhancing data accessibility and query flexibility.

How to use it

Users can now create views that include JSON type columns and query subcolumns without additional workarounds. Simply define views containing JSON columns as usual and query subcolumns directly.
