In this commit, the usage of the tree_support_adaptive_layer_height option was removed:

if (!m_object->config().tree_support_adaptive_layer_height)
        // Adjust support layer heights
        adjust_layer_heights(contact_nodes);

And now this option is not applied anywhere in the code.

I wanted to fix it by adding a check in the TreeSupport::plan_layer_heights() function, but I found another option there (I am new to the project and still learning the codebase) - independent_layer_height, which serves the same purpose.

The tree_support_adaptive_layer_height option is visible in UI, but not working, while the independent_layer_height option is hidden in the UI and has a lot of traces in the code.

I can fix this bug, but I need to know what a better solution can be. As for me, I'd remove tree_support_adaptive_layer_height completely and replace it with independent_layer_height (I'd put it in the same place in UI).
