Description Brent Fulgham 2022-06-13 11:39:02 PDT 
We disable hardware JPEG decoding so that we can block IOSurface uses in the WebContent process. We missed a scenario where using a file picker might need to create an image thumbnail/icon, which now triggers a sandbox violation potentially crashing the WCP.

This patch instructs CoreGraphics to use the software path, similar to how we fixed Bug 238489.
