The NavigationFlagsExtension is used to add navigation flags to an MVF. It adds a single file, navigationFlags.json, to the bundle, which
contains a NavigationFlagDeclarations object. Other extensions may depend on this extension for shared Declarations,
and add utility types like WithFlags or WithFlaggedGeometryAnchor to their schemas.
