    input-settings: Set double click timeout from gsettings
    
    Clutter's evdev input backend has no support for setting double
    click timeout set by gnome-settings-daemon. This results in
    touchpad click events timing out on wayland, because the
    default timeout value wasn't enough.
    
    This patch moves timeout setting to mutter and removes X11
    backend specific setting from clutter.
