Use common source (databinding) for both Settings and OOBE Nav

[Jay-o-Way]

Description of the new feature / enhancement

Let's use one source for the data to build the Navigation in both the Settings window and the OOBE window. See examples in WinUI Gallery or https://learn.microsoft.com/windows/apps/design/controls/navigationview

Scenario when this would be used?

Consistent, centralized code and consistent UX

Supporting information

Also think of the UI strings: with one source, we can use one and the same string for every MenuItem. This will prevent new issues with translations or possibly different strings for the same item. Related to #32479
