List of camera devices does not update on runtime

Tested on iPad Air running iPadOS 17.5.1. Tested using dev-branch of Qt, somewhere between 6.8.0-beta3 and beta4. Tested on the examples 'camera' and 'declarative-camera'.

What happens:
When starting the example without any external webcam connected, the application will not discover any newly connected webcam. The webcam will be discovered if the application is entirely restarted.

If you start the application with a webcam, and then disconnect that webcam, the camera will still appear in the list of camera-devices and the camera-preview will be frozen on the last frame that appeared on the camera that was disconnected.

What do you expect to happen:
I expect the camera to be immediately discovered when I plug it in. If unplugged, I expect the device to disappear from the list of camera devices. Additionally, I expect the application to automatically select another camera to display, if any is available.
