AssetFileDescriptor augments a ParcelFileDescriptor with details about how it should be interpreted, so extend it to support a Bundle of extras. Then use these extras to share thumbnail orientation metadata. The raw image data of EXIF thumbnails matches the orientation of the enclosing image, but the thumbnail data doesn't repeat the EXIF flags. This meant that receivers of openDocumentThumbnail() would get an image that needed to be transformed, but without enough context to actually transform it. Instead of transforming and recompressing the image on the fly on the provider side, send a transformation hint that the receiver side can interpret.
