til::color will help us move away from COLORREF internally. It supports conversion to/from COLORREF, and from all types of structs containing members named R, G, B and A (or r, g, b, and a). ## Validation Steps Performed Tests; run through profile/colorScheme deserialization with `til::color` instead of `uint32_t` or `COLORREF`.
