    wayland: Repick (again) on pointer motion
    
    Unfortunately there's situations where we can't fully rely on only
    crossing events here. One such situation is pointer visibility changes
    due to touch interaction, or e.g. after closing the lid.
    
    In these situations the pointer position stays the same, picks the
    same actor, yet we want to see the right surface as the pointer focus
    again in the wayland side.
    
    This used to happen on the first motion event after the pointer
    visibility change before commit ad3f2b0b863, use motion events again
    for picking so we don't break these usecases.
