Use different members for storing wxBitmap and wxIcon instead of using a single pointer for storing a heap-allocated copy of either of them because this is simpler, more efficient due to avoiding unnecessary conversions and RTTI, and will be simpler to generalize to using wxBitmapBundle instead of wxBitmap in the upcoming commits. As a side effect, don't assert in GetIcon() or GetBitmap() if there is no valid icon or bitmap, as this is inconsistent with the other ports and wasn't even consistent between these functions in wxMSW itself. There should be no other changes in behaviour.
