compositor: deprecate cms-static and cms-colord plugins

While developing the new color management, keeping these old plugins
working would require extra work. Let's deprecate these to see if anyone
cares about them, pending removal after the Weston 11.0.0 release.

CI will keep building these in the "Full build" configuration only. Doc
and no-GL builds are no different for these plugins, so there these are
no longer built.
