  REGRESSION(260471 at main): The platform graphics context colorspace should not be adopted
https://bugs.webkit.org/show_bug.cgi?id=252629
rdar://105637444

Reviewed by Darin Adler.

When storing the return raw pointer of CGIOSurfaceContextGetColorSpace() or
CGBitmapContextGetColorSpace() in a RetainPtr, we should not be using adoptCF().
The refcount of the colorspace should be incremented when WebKit references it.

(WebCore::GraphicsContextCG::colorSpace const):
