Deprecate (and ignore) SkAndroidCodec::ExifOrientation

This was originally added so that some clients (BitmapFactory,
BitmapRegionDecoder) could ignore exif for backwards compatibility, and
others (ImageDecoder) could respect it.

With the addition of NDK APIs for decoding all frames of an animated
image, hwui/ImageDecoder will handle compositing frames, including
handling the orientation, so it may as well always handle it.

This removes tests for SkAndroidCodec that are no longer applicable.
Android already has tests for most of them.
AndroidCodec_sampledOrientation is recreated in
ag/Ieda439910ae52e609f0710d424503616d99ae5c7.
