Move calls to conversion_possible to SkCodec

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
