After this change, LibWeb now expects Web::ImageDecoding::Decoder to be pre-initialized with a concrete implementation before using the webpage. The previous implementation, based on the ImageDecoder service, has been provided directly through an adapter in LibWebClient, and is now used as the default value by WebContent.
