Add Options to SkDecodingImageGenerator, simplify API. Motivation: We want to remove redundant classes from Skia. To that end we want to remove SkImageRef and its subclasses and replace their uses with SkDiscardablePixelRef + SkDecodingImageGenerator. Since Android uses SkImageRef, we need to make sure that SkDecodingImageGenerator allows all of the settings that Android exposes in BitmapFactory.Options. To that end, we have created an Options struct for the SkDecodingImageGenerator which lets the client of the generator set sample size, dithering, and bitmap config. We have made the SkDecodingImageGenerator constructor private and replaced the SkDecodingImageGenerator::Install functions with a SkDecodingImageGenerator::Create functions (one for SkData and one for SkStream) which now take a SkDecodingImageGenerator::Options struct. Also added a ImageDecoderOptions test which loops through a list of sets of options and tries them on a set of 5 small encoded images. Also updated several users of SkDecodingImageGenerator::Install to follow new call signature - gm/factory.cpp, LazyDecodeBitmap.cpp, and PictureTest.cpp, CachedDecodingPixelRefTest.cpp. We also added a new ImprovedBitmapFactory Test which simulates the exact function that Android will need to modify to use this, installPixelRef() in BitmapFactory.
