    gccrs: refactor: update constructor to initialize ExternalItem base class
    
    In full constructor, add initialization for ExternalItem base class. Use
    the node id inside ExternalItem to populate member node id.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-macro.h: add initialization for ExternalItem base
