QWidgetWindow: Forward incoming events with their original spontaneous state

The events may come from QPA, as spontaneous events, or from other parts
of Qt, as non-spontaneous events. We should keep the state of the original
event.

Introduces QCoreApplication::forwardEvent() as a wrapper around the
opaquely named notifyInternal2. Ideally this would be the behavior of
sendEvent, with an enum argument to override the flag, but that ship
has sailed.
