* friends: INotificationService Implementation of GetEvent

According to the RE, the event isn't signaled when handle is returned.
```C
long nn::friends::detail::service::NotificationService::GetEvent(long this, uint *output_handle)
{
  long inner_struct_event;
  int result;

  if (this->event_created)
  {
    inner_struct_event = &this->event_object;
  }
  else
  {
    inner_struct_event = &this->event_object;
    result = CreateEvent(&this->event_object, 0, 1);

    if ( result )
    {
      Assert();
    }

    this->event_created = true;
  }

  uint event_handle = nn::os::detail::DetachReadableHandleOfInterProcessEvent(inner_struct_event);

  *output_handle = event_handle;
  int unknown = *((char *)output_handle + 4);
  *((char *)output_handle + 4) = 1;

  if (unknown)
  {
    CloseHandle(*output_handle);
  }

  return 0LL;
}
```
