Added an examples test app activity to show Maps SDK + Nav SDK only combo

<changelog>Added a 1.0.0 test app activity to show Maps SDK + Nav SDK only combo.</changelog>

Description

Adds a new test app example to show how only the Navigation SDK can be used with the Maps SDK.

• I have added any issue links
• I have added all related labels (bug, feature, new API(s), SEMVER, etc.)
• I have added the appropriate milestone and project boards

Goal

To show how the 1.0.0 Navigation SDK can be purely combined with the Maps SDK, with no usage of the 1.0.0 Navigation UI SDK. The test app's BasicNavigationActivity is definitely basic, but it still uses NavigationMapboxMap, which is a part of the Navigation UI SDK. Many other examples use NavigationMapboxMap.

Implementation

The example added in this pr uses the:

• Maps SDK's MapboxMap
• LocationComponent to show the device location
• Navigation SDK to request a route from the device location to wherever the map is long clicked
• Maps SDK to show the Navigation SDK's route via a gradient styled Maps SDK LineLayer
