This CL teaches drm_util to wire the TransferID and PrimaryID
from the parsed EDID to the gfx::ColorSpace. ColorSpace also
gets a new constructor here, to allow for specifying of a given
TransferID by name (which might be more performant than detailing
the actual function).

Histograms are added, unit tests extended.

Also took the chance to fix a teeny mistake in the EDID blob used
for edid_parser_unittest.cc, and that was landed in the predecessor
CL.
