xcb: respect QEventLoop::ExcludeUserInputEvents in native event handlers

This was a regression from Qt 4.

Before this patch, we supported filtering events only at QWindowSystemInterface
level, but to properly support filtering in QAbstractEventDispatcher::filterNativeEvent,
we have to filter the events earlier. Now it is possible to enable/disable this
feature for platforms that support native event filtering.

The mapping of which events are user input events were taken from
QWindowSystemInterfacePrivate::EventType.
