[TIMOB-24205] iOS: Ti.Media.CAMERA_AUTHORIZATION_* permissions are `undefined` in some 6.0.0.GA cases

The Ti.Media.CAMERA_AUTHORIZATION_* constants are no longer defined. They all return undefined. Code like the following worked in our app up till 5.5.x. Updating to 6.0.0.GA it fails to recognize that the user has already granted permission.

switch (Ti.Media.cameraAuthorization) {
  case Ti.Media.CAMERA_AUTHORIZATION_AUTHORIZED:
    // camera permissions granted, do something like
    Ti.Media.showCamera();
    break;
  case Ti.Media.CAMERA_AUTHORIZATION_DENIED:
  case Ti.Media.CAMERA_AUTHORIZATION_RESTRICTED:
    // they have denied access to the camera
    alert('You denied camera permission. Use Settings to grant them');
    break;
  default:
  	// they'll be prompted for perms...
}

console.log(Ti.Media.cameraAuthorization); // => 3
console.log(Ti.Media.CAMERA_AUTHORIZATION_AUTHORIZED); // => undefined
console.log(Ti.Media.CAMERA_AUTHORIZATION_DENIED); // => undefined

TIMOB-17812 shows a similar way to use these constants. Our app has been using them since iOS8 was first released. They are still documented in the Ti.Media pages. I see nothing in the 6.x release notes about them being removed. The following code works, but is not equivalent. For example, it won't let me differentiate between a user who has not yet granted permissions and one who has explicitly denied permissions. That means I can't show them a custom app dialog to tell them what great features they're missing by having denied permissions.

if (OS_IOS) {
    if (Ti.Media.hasCameraPermissions()) {
      // yay!
    } else {
      // boo hoo
    }
}
