Adds a plumbing layer manifold (#57494)

Adds a multilayer plumbing manifold, I also murdered the multilayer duct

You can now alt-click the plumbing RCD to change the layer it prints. I made a whole thing where right clicking changed the settings and you could use that to change machinery aswell. I even did that with the plunger, it was absolutely beautiful. Anyway that drained the life out of me because apparently there's no attack_obj_secondary and afterattack_secondary ALSO called attack_obj (left click). I just hate whoever made it with intensity

Plumbing now uses three layers. They should be easier to navigate. I tried to make layer connecting the same as cross-color connecting, but that would take more of my soul then there is to take
