Inefficient use of MapboxRouteLineApi cache for restricted sections

还没有人认领这个 Issue。

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` locally in `MapboxRouteLineApi` and refresh it whenever routes are re-drawn. We already follow the same practice with the `List`:
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

从 MapboxRouteLineApi.kt 中的 updateTraveledRouteLine 和 setNavigationRoutes 开始，然后检查 MapboxRouteLineUtils.kt，其中会缓存 ExtractedRouteData。在 MapboxRouteLineApi 中本地保存提取出的路线数据，并在路线重新绘制时刷新这些数据，这样消失点更新就不再需要重新计算开销很大的路线哈希和缓存查找。
