Each of the backends becomes a plugin. This allows kwin_wayland to load the requested plugin and kwin itself doesn't need to link all the libraries needed. E.g. libdrm is no longer linked if running kwin_x11. Also this allows to create backends for the non-standard EGL platforms (examples could be raspberrypi or Android devices).
