Drop win32_message_dialog()s

There doesn't seem to be much need for these and they look a little
different from the rest of Geany (or a lot different when Windows
uses the dark theme and Geany the light one). Before removing the native
win32 file open dialogs, win32_message_dialog() was called from the native
file dialog implementations so its presence was necessary but I think
normal GTK dialogs will serve their purpose well.
