In some circumstances we could call wxApp::OnExit() before destroying the application windows, which violated the documented (and reasonably expected) behaviour.

Fix this by adding a wrapper CallOnExit() function which destroys all windows before calling OnExit() and, for good measure, then does it again in case the user-overridden version of this function created more windows when it was called.

This also has a nice side effect of freeing the user code from the need to call the base OnExit(), as it is now trivial and doesn't do anything any more.

Closes #26172.
