Move static colors to partial struct and add two colors

[sleepyyapril]

Added:
Gluon Grey (known as #1B1B1E everywhere in content. RGB: 27, 27, 30, 255)
Noble Black (known as #202025 everywhere in content. RGB: 32, 32, 37, 255)

Moved static colors to a separate partial struct.

would you rather Muted Deep Blue Canyon and Muted Deep Blue Opal

names are fine, IMO ideally there should be some sort of doc, because the rest of the system colours are MS Color values [Even some sort of "Robust" reference would maybe be good but this is really nitpicky.]
References to a slight blue tint probably good, but whatever the names are I'll cope 👍

[One question I do have is whether this is best suited for RT or content - it seems to all be content-side, and projects apart from SS14 might want different UI theming, not that an extra constant is a huge deal.]

I suppose it doesn't really hurt anything having more static colors in engine, but it might be more appropriate to define these as extension properties in content.

Edit: I just noticed the frozen dictionaries. That makes things a bit trickier. It might be best to do this here in the engine then.

Yeah thats why I did it. Not sure if that's the best solution imho
