Android: Crash if switching between cameras without first stopping the camera preview

[jasells]

tested on Android 13 (Pixel 4) + Android 15 (Samsung Galaxy-S24)
On current main, if I switch between cameras enough, eventually (swap cams 2-3x at most) I will get this:

In the repo's test app: tap Stop Camera btn before switching cameras will avoid this issue.

I solved A similar scenario in a custom app where the camera switch was on a dedicated settingsPage by stopping the camera before leaving the page that hosts the CameraView like:

 protected override async void OnDisappearing(Page s, EventArgs e)
 {

     // in case the camera view is still recording, stop it. This can also cause crashes on Droid if not awaited before unloading the control's parent view/page
     await CameraView.StopCameraAsync();

     // turn off the preview to prevent crashes on Android when native code tries to get a ref to the view that is no longer on screen
     CameraView.AutoStartPreview = false;
}
