    gccrs: Add global scope debug function for crate
    
    A crate is not a visitable and thus cannot be used with the debug
    function. Until it is made visitable this commit provides a function
    to dump the content of a crate.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-dump.cc (debug): Add debug function which calls debug
            on every crate field.
            * ast/rust-ast-dump.h (debug): Add function prototype.
