Description Said Abou-Hallawa 2021-01-31 15:00:35 PST 
Transcoding the HEIF images requires loading the HEIF reader symbols which is not happening in macOS Catalina. The bug has been fixed in the underlaying frameworks of macOS Big Sur. But since the trunk WebKit can run on macOS Catalina, we need a workaround for this bug in WebKit itself.

This should probably reference the ImageIO radar.

The workaround should be scoped only to OS versions where the underlying bug is not fixed, so that this code naturally evaporates when the fix is globally available. Other than that, this seems reasonable.

Also, you only need to run it once per process.

I tried to come up with a concise alternative HAVE name that mentioned the behavior instead of the radar # and came up empty (or with paragraphs).
