    gccrs: Fix type param bound parsing with opening scope
    
    The function parsing type param bounds had a problem with scope
    resolution opening token.
    
    gcc/rust/ChangeLog:
    
            * parse/rust-parse-impl.h (Parser::parse_type_param_bound): Add missing
            case for lifetime switch.
