navigation sdk integration (android + ios)

Extend mapbox view with the navigation sdk integration

Here is how it looks with my implementation: at Android https://youtube.com/shorts/VItnracOUAU

at iOS https://youtube.com/shorts/t9QlqxOJm1Q?feature=share

In this version I've integrated Mapbox Navigation SDK 3.5.0 into the current Mapbox View widget without Navigation UI (I think navigation ui componenets must be exposed in separete flutter package).

Besides, this version expose NavigationLocationProvider which allows to fetch current user location when process running on background.

However, I have to notice a few things:

• I don't think this PR will ever be merged, however, it could be used as inspiration for the user who are waiting for Mapbox iplemnetation of the same feature.
• I am C# dotnet developer, and I have a doubts that I did this android version right
