This is part of an effort to distinguish between different types of contexts in GPU Skia. When using a DeferredDisplayList (DDL) recorder, the context you get is not a direct context and cannot be used for operations like uploading or reading textures. Since Android does not use DDLs, it is not directly affected by this change but other APIs, such as SkImage::MakeFromTexture are being migrated to require a GrDirectContext to increase sanity.
