Vlad Zahorodnii 8baf535a7a xwayland: Make DataBridge a native event filter
With the DataBridge being a native event filter, we can further separate
DataBridge-specific and generic Xwayland bits. In particular, we no
longer have to call DataBridge::filterEvent() from the dispatchEvents()
method, whose main purpose is to dispatch X11 events to kwin.
