tests/clutter: Add color-state-transform test
The steps for this test:
* For each testing color create an actor and assign the color to it.
* Create a src_color_state and set it to all actors.
* Create a target_color_state and set it to the stage_view.
* Wait for paint.
* Read the color for each actor which will be different after the
color-state transformation.
* Do the same transformation on CPU for each test color.
* Validate that the resulting colors match.
In the future this test will be extended to compare transformations
between color_state_params and color_state_icc.
