fix: add node wrapping for A_Expr, BoolExpr, Alias, Boolean in v15-to-v16 transformer

- Fixed A_Expr with proper name, lexpr, rexpr transformation
- Fixed BoolExpr with args array transformation
- Fixed Alias with colnames array transformation
- Fixed Boolean with boolval field transformation
- Continuing systematic node wrapping approach following v13-to-v14 patterns
