Description Jean-Yves Avenard [:jya] 2022-06-13 23:40:05 PDT

Photos on iCloud.com appear black in iOS 16, works with iOS 15.

Cause: 

RemoteImageDecoderAVF::createFrameImageAtIndex uses a call to IOSurface::createFromSendRight IOKit which is blocked by the sandbox in the content process.

We should stop using IOkit methods from the content process.
