environment agnostic {mode}_list render mode

[younik]

After #3040, it makes sense to handle frame collection modes with a simple Wrapper (similar to HumanRendering).
This allows environments that can work with single rendering to support frame collection modes for free, while other environments can still define their own behavior by simply adding rgb_array_list (or whatever) to metadata.

This PR:

• Removes Renderer util in favor of the new Wrapper RenderCollection
• If an environment supports rgb_array (or another mode), it should not do anything to support rgb_array_list (or mode_list), because during making the environment will be wrapped with RenderCollection that will handle it
• If an environment needs custom code for rgb_array_list, it can add rgb_array_list in metadata and the RenderCollection wrapper will not be applied. In this case, the environment should handle internally the mode rgb_array_list.
