Tabletop AR: Add camera feed

[hud10837]

Related to issue: https://devtopia.esri.com/runtime/kotlin/issues/4436

Description:

Adds a camera feed to the TableTopSceneView component. This PR adds all of the render code from the prototype, and much of the code comes from the HelloAR example from Google. It's expected that some of this code will change and be pared down, but the purpose of this PR is to have a working example of a SceneView rendering on top of a camera feed.

Summary of changes:

• Add camera feed and associated rendering components via ArSurfaceView
• Add assets related to displaying the camera feed, ie. shaders
• Add the ArSurfaceView to the TableTopSceneView
• Modify the microapp to set up an ARCore session and call the TableTopSceneView. Note that this code will be moved in a future PR to internal component code in the TableTopSceneView.
