    wayland: Do not store the grab cursor separately
    
    After the grab is finished, we would expect an enter event, and
    GDK updating internally the cursor for that window and device.
    This means there is no need at all to store it separately in the
    backend.
    
    As a side effect, animated cursors are now also possible on grab
    icons.
