Andreas Kling cd7262ee56 LibWeb+LibWebView+WebContent: Add Web::Platform::ImageCodecPlugin
This replaces the previous Web::ImageDecoding::Decoder interface.
While we're doing this, also move the SerenityOS implementation of this
interface from LibWebView to WebContent. That means we no longer have to
link with LibImageDecoderClient in applications that use a web view.
