Reviewed by Simon Fraser.

The change in https://commits.webkit.org/262607@main has caused an
occasional out of memory exception to be thrown in CGDataProviderCopyData.
Catch and ignore this exception, while bailing out of the method.

I've added some logging to give more information if we see it again.

This involved changing a .cpp file to .mm.
