Pratik Dey d1d720d08a feat(nodejs): support field/data type input in add_columns() method (#3114 )

Add support for passing field/data type information into add_columns()
method, bringing parity with Python bindings. The method now accepts:

- AddColumnsSql[] - SQL expressions (existing functionality)
- Field - single Arrow field with explicit data type
- Field[] - array of Arrow fields with explicit data types
- Schema - Arrow schema with explicit data types

New columns added via Field/Schema are initialized with null values. All
field-based columns must be nullable due to null initialization.

Resolves #3107
