Move common code into the base class, so subclasses need not call
conversion_possible.
Use SkEncodedInfo rather than SkImageInfo, and use the proper frame.
API Changes:
- SkAndroidCodec:
- Add getEncodedInfo(), for SkBitmapRegionCodec
- SkEncodedInfo:
- Add opaque() helper
- SkBitmapRegionDecoder:
- Remove unused conversionSupported
