derive(SmartPointer): register helper attributes Fix rust-lang#128888 This PR enables built-in macros to register helper attributes, if any, to support correct name resolution in the correct lexical scope under the macros. Also, `#[pointee]` is moved into the scope under `derive(SmartPointer)`. cc `@Darksonn` `@davidtwco`
