Add no-loc tags to registry value names in Windows 11 settings reference

Localized versions (ja-jp) were translating registry value names like
AllowFailover, AutoGameModeEnabled, and SelectedThemeName into the
target language, making the documentation unusable for developers who
need the exact English registry identifiers.

Changes:
- Wrap ~50 registry value names in :::no-loc::: tags
- Wrap 15 theme string literals in :::no-loc::: tags
- Use backtick code formatting for enum/struct API names
- Fix swapped descriptions for VKTakeScreenshot/VKSaveHistoricalVideo
- Fix typo: 'chose' -> 'choose'
- Fix grammar: 'Indicates in multilingual' -> 'Indicates if multilingual'
- Fix missing leading pipe on RandomMacState table row
- Update ms.date

Addresses UUF items #491550 and #502032.
