[CG/FUI] CG's FlatUI library, made for pre-boot/pre-user environements.

- FlatUI is used to install ZKA for example.
- Or to indicate an error (using the ke_stop call).
- Or to show a popup saying that system couldn't boot.

The FlatUI's style will be replicated in user space as well, for
consistency.
