SDL_GetCameraPermissionState - Query if camera access has been approved by the user.

       This function is available since SDL 3.2.0.

       Cameras  will  not function between when the device is opened by the app and when the user permits access
       to the hardware. On some platforms, this presents as a popup dialog where  the  user  has  to  explicitly
       approve access; on others the approval might be implicit and not alert the user at all.

       This  function  can  be  used to check the status of that approval. It will return 0 if still waiting for
       user response, 1 if the camera is approved for use, and -1 if the user denied access.

       Instead of  polling  with  this  function,  you  can  wait  for  a  SDL_EVENT_CAMERA_DEVICE_APPROVED  (or
       SDL_EVENT_CAMERA_DEVICE_DENIED) event in the standard SDL event loop, which is guaranteed to be sent once
       when permission to use the camera is decided.

       If a camera is declined, there's nothing to be done but call SDL_CloseCamera() to dispose of it.

       SDL_GetCameraPermissionState - Query if camera access has been approved by the user.

       Returns -1 if user denied access to the camera, 1 if user approved access, 0 if no decision has been made
