    Add shell_write_string_to_stream()
    
    Add a helper function to write a string as UTF-8 to a GOutputStream.
    The signature of GOutputStream:
    
     gboolean g_output_stream_write_all (GOutputStream *stream,
                                         const void *buffer,
                                         gsize count,
                                         gsize *bytes_written,
                                         GCancellable *cancellable,
                                         GError **error);
    
    Can't currently be handled by GJS.
