    gccrs: Add unsafety member to modules
    
    The rust syntax allows unsafe module even if those are rejected at a
    later stage.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-item.h: Add safety status to Modules in the AST.
            * parse/rust-parse-impl.h (Parser::parse_module): Adapt constructors.
