Add wxFileDialog::GetCurrentlySelectedFilterIndex() similar to the existing GetCurrentlySelectedFilename(), which can be used to retrieve the index of the currently selected filter and update the state of the extra controls in wxFileDialog accordingly. Implement this for wxMSW only by updating the internally stored value from the native CDN_TYPECHANGE notification and also generating a wxEVT_UPDATE_UI event to allow the extra controls to update themselves. Closes https://github.com/wxWidgets/wxWidgets/pull/1310
