output: add color_format state field

Browse source 
Adds wlr_output_color_format (AUTO, RGB444, YCBCR444, YCBCR422,
YCBCR420) matching the DRM connector color format property. The DRM
backend discovers and sets this property on modeset.

The wlr-output-management-unstable-v1 protocol is extended to version 5
with a color_format enum and set_color_format request, allowing clients
to configure the output color encoding.
