More color space improvements to DM

Added P3 configs (tagged surface and SkColorSpaceXformCanvas)

Added logic to tag the output PNGs when using a xform canvas,
so the images look correct in Chrome (and work correctly with
skdiff).

We don't use the gamma_correct tag for much in gold, but only
set it for outputs with a linear transfer function.
