WTR: Avoid conversion from platform image to WKImage and then to platform image again when dumping pixel results

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

When dumping pixels from a web view snapshot, we create a platform image that is then converted to a WKImage, which is a ShareableBitmap, so the image is rendered into a graphics context. Then we immediately extract the platform image back from the WKImage to dump the pixels. We could avoid that conversion by taking the web snapshot from TestInvocation::dumpPixelsAndCompareWithExpected().

hmm, it seems the iOS changes are not correct, I'll try to figure out

I think the problem in iOS is that we were releasing CARenderServerBufferRef too early, so I've added a callback to CGDataProviderCreateWithData and moved the call to CARenderServerDestroyBuffer there.
