Ladybird/Android: Create a service for ImageDecoder
This follows the pattern for the other services spawned by WebContent. The notable quirk about this service is that it's actually spawned by the ImageCodecPlugin rather than in main.cpp in the non-Android port. As a result we needed to do some ifdef surgery to get all the pieces in place. But we can now load images in the Android port again :^).
