winewayland.drv: Forward all client surface pointer events to parent.

Set an empty input region for the client area surface, so that the compositor forwards input events to the main/parent surface instead. This simplifies input handling, since otherwise we would need to implement special handling of events on the client area surface and transform them accordingly.
