Move reinitializeCompositing and restartKWin into the Compositor
The DBus signal which causes KWin to reinitialize the Compositor is moved into the Compositor as everything can be handled from there as well. This comes together with moving the restartKWin functionality into the Compositor as it is only relevant there. Restart will only happen if the wrong Qt graphicssystem is used for the chosen compositing backend.
