macOS: Remove workaround for queued input events to stale windows

We now track the platform window with a QPointer, so the event callbacks
can (and do) check the validity of the platform window before passing
them on. The window property of the NSView is also nil at the point of
even delivery, if we need another way to check if the event is still
valid.
