SkDecodingImageGenerator now uses SkStreamRewindable

This makes sense since Android will be giving us a stream and the
decoders expect a stream.  This also removes some glue code,
DecodeMemoryToTarget, that works better using a SkImageGenerator.

Motivation: This is a necessary step to move from SkImageRef to
SkDiscardablePixelRef.

SkImageDecoder::DecodeMemoryToTarget function removed.
