File Explorer: Added option to disable the modern navigation bar (FEMNB).

- The code for disabling tabs (TIFE) is also there, but it doesn't work on 22621.2506+ -- it fallbacks to the Windows 10 Ribbon instead so I'm hiding it for now.
- This should also fix window position saving when using Windows 10 Ribbon on builds with TIFE enabled, up to 23570 (Dev).
