KDE_INSTALL_KXMLGUIDIR: undocument and prepare remove for 6.0
ui.rc are considered config files rather than data files. Therefore for KF6 the location will be cnahged to be based on KDE_INSTALL_CONFDIR, but with the component/app name as first order element in the subdir:
DATAROOTDIR/kxmlgui5/<component>
->
CONFDIR/<component>/kxmlgui6
So users will have to compose the full dir themselves in case they want a file path instead of deploying as Qt resource file, based on KDEInstallDir's provided KDE_INSTALL_CONFDIR.
