[bijiben] lazy-serializer: Port to G_DECLARE_FINAL_TYPE

[Mohammed Sadiq <pksadiq src gnome org>]

commit 4d7f331698a415b878645a587d5197e02fd1ef87
Author: Mohammed Sadiq <sadiq sadiqpk org>

    lazy-serializer: Port to G_DECLARE_FINAL_TYPE
    
    * Use G_DECLARE_FINAL_TYPE to avoid boilerplate code
    * Don't use private members.
      This class isn't derivable. So there isn't any difference.
    
    This is a part of effort to clean up codebase and make the code more
    maintainable.
