Use CameraX on Android to take a picture

[tomasMizera]

Camera intents to capture a picture are deprecated now. We should slowly migrate to use CameraX.

The API seems minimal, but some investigation must be done as it might use the Android fragments (:-/)

As it turns out, Camera intents are not deprecated, Camera 1 is deprecated. See https://developer.android.com/media/camera/camera-intents

We might want to implement the camera ourselves though via Qt API
