[mutter/wip/carlosg/xwayland-on-demand: 12/28] core: Ensure passive key grabs are only set up on X11

    core: Ensure passive key grabs are only set up on X11
    
    We don't strictly need it for wayland compositors, yet there are
    paths where we try to trigger those passive grabs there. Just
    skip those on the high level code (where "is it x11" decisions
    are taken) like we do with passive button grabs.
