feat(i18n,ui): externalize TUN settings labels, add translations

- Replace hard-coded labels "Auto Route", "Strict Route", "Stack",
  and "Mtu/mtu" with resource keys in both Avalonia and WPF views:
  - v2rayN/v2rayN.Desktop/Views/AddServerWindow.axaml
  - v2rayN/v2rayN.Desktop/Views/OptionSettingWindow.axaml
  - v2rayN/v2rayN/Views/AddServerWindow.xaml
  - v2rayN/v2rayN/Views/OptionSettingWindow.xaml
- Add new resource keys in ResUI:
  TbSettingsTunAutoRoute, TbSettingsTunStrictRoute,
  TbSettingsTunStack, TbSettingsTunMtu (unified casing as "MTU").
  Files:
  - v2rayN/ServiceLib/Resx/ResUI.resx
- Provide translations in:
  - v2rayN/ServiceLib/Resx/ResUI.ru.resx
  - v2rayN/ServiceLib/Resx/ResUI.zh-Hans.resx
  - v2rayN/ServiceLib/Resx/ResUI.zh-Hant.resx
  - v2rayN/ServiceLib/Resx/ResUI.fa-Ir.resx
  - v2rayN/ServiceLib/Resx/ResUI.hu.resx
- Normalize XML comments/whitespace in .resx files.
- Update submodule v2rayN/GlobalHotKeys to 5201dd5.

No breaking changes.
