This method replaces the X-KDE-ORDERING property in the Effect's desktop files. This change is a preparation step for integrating the new Effect Loader which doesn't read the ordering information. Thus it needs to be provided by the Effect itself so that the EffectsHandler can properly insert it into the chain. Also for the built-in Effects on the long run it doesn't make much sense to install the desktop files. And binary plugin effects will migrate to json metadata which also doesn't have the KService::Ptr. Thus overall it simplifies to read this information directly from the Effect.
