[GPU Process] Ensure that only supported image decoders run in the WebProcess
https://bugs.webkit.org/show_bug.cgi?id=256852
rdar://109414332
Reviewed by Brent Fulgham.
Ensure that ImageIO is allowed to decode only the (default + additional)
supported
image types even outside WebKit rendering code path for example displaying a
bitmap
image in a PDF document.
This work will be done for WK2 only. WK1 allows setting the prefrences only
after
creating the WebView. And we use the prefrences to set the additional supported
image types. So there is no way to pass to know additional supported image types
when the WebView is created. And ImageIO expects
CGImageSourceSetAllowableTypes()
to be called only once.
