[PATCH i-g-t v4 6/8] tests/kms_properties: check colorop properties on active color pipelines

A colorop property can only be changed if its color pipeline is active,
i.e. the colorop is in the chain of the color pipeline set in the plane
COLOR_PIPELINE property and the plane is active. Set each color pipeline
active before checking the properties of its colorops, and restore
Bypass afterwards.
