scroggo 1c005e4a38 Create a scanline decoder without creating a codec 
Prior to this CL, if a client wanted to decode scanlines, they had to
create an SkCodec in order to get an SkScanlineDecoder. This introduces
complications if input data is not easily shared between the two
objects.

Instead, add methods to SkScanlineDecoder for creating a new one from
input data, and remove the creation functions from SkCodec.

Update DM and tests.
