IPA/AD/SDAP/BE: Generate refresh callbacks with a macro
    
    Related: https://pagure.io/SSSD/sssd/issue/4012
    
    The per-object type refresh functions are more or less boilerplate code.
    Even though macro-generated code should be used very rarely, here the
    generated code does not contain any logic at all so it makese sense to
    generate it with macros.
