[Navigation][TabBar][NavView] Avoid using reflection when navigating through tabs with a region attached

[erikvilima]

What would you like to be added:

When navigating using a TabBar or NavigationView with a Grid to hold the content of its items, it would be great if reflection was not used, since the items are already there.

As an example we have the code shown in the docs:

NavigationView
TabBar

If there are no RouteMaps for the tabs, when preparing the request to navigate Navigation goes searching for a view or view model to dynamically create a RouteInfo for that navigation. But there would be no views nor VMs associated there. So in the end it ends up creating a RouteInfo with only the path here.

Why is this needed:

For which Platform:
