We already know how to talk to the network_service from Dart via fetch.dart. Might as well use that for Image loading as well insetad of having ImageLoader do it. As part of this I've renamed *ImageLoader to *ImageDecoder and moved all the image loading logic into Dart. This required me to teach the idl system about mojo handles so that I could pass the resulting MojoHandle from fetch.dart up through to ImageDecoder.
