Detect all named gammas

Our DstColorSpace UMA is showing some named gammas that are
not appropriately detected and placed in named categories.
https://uma.googleplex.com/p/chrome/histograms?endDate=latest&dayCount=1&histograms=Blink.ColorSpace.Destination&fixupData=true&showMax=true&filters=isofficial%2Ceq%2CTrue&implicitFilters=isofficial

This CL should fix that.

I'm not sure (yet) how I feel about this landing permanently.
Seems a little messy.

But it will be interesting to see how this affects the UMA.
My best guess is that we are hitting this case when all
three gammas are "invalid" in different ways.  I'm expecting
to see some profiles end up in the "invalid" category now.

It's also possible that we'll see these cases being absorbed
into sRGB or somewhere else.
