Various improvements to CodecSrc testing in dm

*** Add CodecMode and ScaledCodecMode (in place of
NormalMode), so now we test SkCodec's getPixels() and
SkScaledCodec's getPixels()

*** Don't attempt to test scanline and codec modes using
the dimensions that were recommended for SkScaledCodec.

*** Change tags so that each scale gets its own output
folder.

TODO: Make ScanlineMode and ScanlineSubsetMode support
kOutOfOrder etc.  I think this belongs with the gif CL -
I don't want to add test modes that we don't run yet.
