Bug: skia:8076 Move SkImageGeneratorCG and SkImageGeneratorWIC to include/ports/, and make them SK_API. Remove SkImageGeneratorCG::NewFromEncodedCG. No known clients are using it, and it was a private API in src/. There is already a MakeFromEncodedCG to replace it. Similarly, switch WIC from New to Make. Add a compile test for using them with SetImageGeneratorFromEncodedDataFactory.
