Add support for variable-sized AST nodes for logical and control expression
operations including AND, OR, RETURN, YIELD, and SUPER.
Changes:
- Add variable-sized node structures for expression nodes in node.h
- Add casting and value access macros for expression nodes
- Modify existing expression functions to conditionally use variable-sized versions
- Implement variable-sized node creation functions (new_and_var, new_or_var, etc.)
- Add codegen support for variable-sized expression nodes
- All expression types (AND, OR, RETURN, YIELD, SUPER) now support variable-sized allocation
