exo: Adds a HDR demo wayland client

This is intended to aid the development of the color manager protocol.

The demo program connects to the color manager API, swaps between and
HDR and non-HDR color space, and currently has two modes:

-   Gradient rendering mode (to demo color gamuts)
-   White-on-black box (to demo dynamic range)

BUG=b:192562912

TESTED=The program compiles but fails, and will work as we implement the
protocol. It works conviningly against an in-progress implementation.
