Inefficient use of MapboxRouteLineApi cache for restricted sections

Whenever the MapboxRouteLineApi needs to update the vanishing point (MapboxRouteLineApi#updateTraveledRouteLine), MapboxRouteLineOptions#styleInactiveRouteLegsIndependently is enabled, and the route goes through a visualized restricted section, the API needs to extract the full parsed route object to create the gradient expression for the restricted sections:
https://github.com/mapbox/mapbox-navigation-android/blob/d8d04fe75e53063f5e185c3779c04c7b0914f77d/libnavui-maps/src/main/java/com/mapbox/navigation/ui/maps/route/line/api/MapboxRouteLineApi.kt#L463-L470

This parsed data is already cached in
https://github.com/mapbox/mapbox-navigation-android/blob/d8d04fe75e53063f5e185c3779c04c7b0914f77d/libnavui-maps/src/main/java/com/mapbox/navigation/ui/maps/internal/route/line/MapboxRouteLineUtils.kt#L67-L72
however, the key of this cache is based on the hash of the full DirectionsRoute, which makes computing the key very expensive for long routes.

While this is not as problematic when routes are re-drawn (for each MapboxRouteLineApi#setNavigationRoutes), it is extremely unsuitable for very frequent updates of the vanishing point with MapboxRouteLineApi#updateTraveledRouteLine. This cache lookup on a route from Munich to Madrid can take more than 20% of the main thread's time on a rather powerful Samsung S22+, and on other hardware can even occasionally lead to ANRs if the frequency of the location indicator updates is high enough to flood the main thread.

During the vanishing updates, they cache element is not possible to be changed, so instead of extracting the value from the cache on each update, we should store the List<ExtractedRouteData> locally in MapboxRouteLineApi and refresh it whenever routes are re-drawn. We already follow the same practice with the List<RouteLineExpressionData>:
https://github.com/mapbox/mapbox-navigation-android/blob/d8d04fe75e53063f5e185c3779c04c7b0914f77d/libnavui-maps/src/main/java/com/mapbox/navigation/ui/maps/route/line/api/MapboxRouteLineApi.kt#L199

Start in MapboxRouteLineApi.kt at updateTraveledRouteLine and setNavigationRoutes, then inspect MapboxRouteLineUtils.kt where ExtractedRouteData is cached. Keep the extracted route data locally in MapboxRouteLineApi and refresh it when routes are redrawn, so vanishing-point updates no longer recompute the expensive route hash and cache lookup.
