Go from a 1x2 to a 2x2 dither cell, and change/simplify the logic for how we
compute the "dithered" version of a color to just a graduated fixed-point-round.
Also, add this new dither to conical and sweep, which before had no dithering.

Disabled for now using SK_IGNORE_GRADIENT_DITHER_FIX. Will enable this and
and rebaseline skia.
