color: forbid multiple wp_color_management_surface_v1

Browse source 
After inspecting EGL and Vulkan APIs, there does not seem to be a need
to allow multiple color management extensions on the same wl_surface.

This reduces the chances of application components fighting over who
sets up the image description.

(There is also an unrelated whitespace fix.)
