LibGfx+icc: Print fields that are fourccs registered with the ICC

Namely:
- preferred CMM type
- device manufacturer
- device model
- profile creator

These all have in common that they can take arbitrary values, so I added
a FourCC class to deal with them, instead of using an enum class.
I made distinct types for each of them, so that they aren't accidentally
mixed up.
