support gray8 destinations on CPU

 - fill in a couple switches to allow software to rasterize gray8
 - add a gray8 config to DM so we can test it
 - enable this config on some bots

Today we draw gray8 using SkRasterPipeline, loading it as {g,g,g,1}
and storing using the same fixed luma math as SkLumaColorFilter.
One day it'd be nice to use the color space's luma vector if present.

Can we support this on GPU?
