[GPU Process] (REGRESSION 262607@main): Copy pixels of CGImage only if it is
not a sub-image
https://bugs.webkit.org/show_bug.cgi?id=255677
rdar://108072383
Reviewed by Simon Fraser.
In ShareableBitmap::createFromImagePixels(), CGImage and its CGDataProvider
may disagree about how many bytes are in the pixels buffers. CGImage is most
likely a sub-image of another CGImage which inherits its meta data but not
the full pixels buffer.
In this case we should fallback to ShareableBitmap::createFromImageDraw().
Ortherwise ShareableBitmapConfiguration will falsely describe the data in the
SharedMemory.
