kwin_wayland gains a new command line option to enable libinput support. This is needed as logind blanks the VT when the session controller releases the control. So a nested compositor can seriously affect the primary session. Thus it needs a dedicated command line switch to enable it. By default libinput support is disabled for kwin_x11 and can be enabled for kwin_wayland in case KWin is compiled with libinput support.
