    layout: Move the keybinding mode to the user of PressureBarrier
    
    For the hot corner case, we want to have the pressure apply both in
    and outside of the overview, so we need to move this to the user. At
    the same time, use keybinding mode math that's more like what's used
    in filterKeybinding.
    
    While it may seem like an abuse of the KeyBindingMode API, it may
    become more reasonable if one thinks of the pressure barrier as a
    binding of sorts, just applied to the mouse. If a ButtonBinding API
    was added to mutter, I think we'd use the existing KeyBindingMode
    infastructure there as well.
