Automatic update from web-platform-tests Remove redundant image() tests from css-backgrounds The image(<color>) functional notation is fully covered by the dedicated tests under css-images/ (image-color-* reftests and parsing/image-function-*). Drop the duplicate coverage that had accumulated in css-backgrounds. The light-dark() cases that merely embed image() as an argument are kept, since they exercise light-dark().
