output-management: add color format support

Browse source 
Add a color_format enum and corresponding event/request to
wlr-output-management-unstable-v1 (version 5). The enum mirrors
the DRM connector color format property, allowing clients to
read the current color encoding (RGB, YCbCr 4:4:4, 4:2:2, 4:2:0)
and request a change. Compositors should ignore set_color_format
if the connector lacks the property.
