Support for rotation on Android and iPhone in samples

[gb2111]

Feature Description

Camera and pose detection will rotate accordingly to screen orientation.

Current Behaviour/State

Currently pose detection and camera are aligned only with the initial screen orientation. When you rotate further, the camera preview is not as one would expect in the phone app. Below photo shows app initialized in portrait mode and then rotated to horizontal.

Additional Context

No response

I am not planning to change this behavior as I am using the sample app to test the behavior when the device is rotated.

At least, I think this is not essential for the sample app, so the priority is low.
