• Node panels feature for node groups and built-in nodes (#108895)

  Panels can be used to group sockets in a collapsible section. They can be added to node groups and to built-in nodes.

• Group sockets are managed in new UI tree view together with panels. Drag-and-drop support for ordering sockets and inserting into panels.
• Breaking API changes:
  • Node group API moves from NodeTree to NodeTree.interface.

• Custom nodes (aka. "python nodes"): NodeSocket.draw_color_simple callback becomes the preferred color function for custom socket types.

  It does not take a context or node instance but that is sufficient for most use cases. The new callback is used in cases where concrete node instance exists, for example drawing node group interfaces.
