Send ShortcutOverride event when receiving a non-spontaneous key press

When a key press is received which is not spontaneous then it needs to
be manually sent as a shortcut override event to ensure that any
matching shortcut is triggered first. This enables emulation/playback
of recorded events to still have the same effect.

[ChangeLog][QtWidgets] Sending a key press event with sendEvent() now
sends a ShortCutOverride event first to the widget to trigger any
shortcuts set first.
