This means that calling wgpu::Object::DoStuff will translate to a call to dawn_native::ObjectBase::APIDoStuff. This will clarify the difference between reentrant calls and internal calls in dawn_native. Avoiding issues in the future. This CL only changes the code generator to prefix with "API", performs renames needed to make the code compile, and adds TODOs for things that should be fixed in follow-up CLs.
