Subject: [PATCH] fix(ast_tools): visit nested objects to add `__proto__:
 NodeProto` in raw transfer codegen (#17230)

Fix a bug in codegen for ESTree walker, where it didn't visit nested objects when it adds `__proto__: NodeProto` to node objects. This doesn't make any difference now, but fixing it is required for next PR (#17231).
