Vadim Zeitlin 926df8a162 Add wxFileDialog::GetCurrentlySelectedFilename().
Also send wxEVT_UPDATE_UI events for the extra controls in wxFileDialog.

The combination of these changes allows extra controls to update their state
depending on the current selection in the dialog. Show a simple example of
doing it in the dialogs sample.

Closes #15235.
