This change modifies the code generation for structs in `bindings.cc`. Instead of placing each struct's constructor and member functions under individual markers, all autogenerated struct source code is now grouped together under a single `// {{ AUTOGENNED_STRUCTS_SOURCE }}` marker. This improves the organization of the generated file and simplifies the template.
Future work would move the rest of the structs into this pattern
