Issue description

Working through building a GDExtension that provides a custom Node3D, along with an EditorPlugin, I've found the following functions that are missing from godot-cpp that are available to modules inside Godot.

• SceneTree.get_debug_collision_material()
  • helpful for drawing collision shapes
  • no other way found to get this from the godot engine
• NavigationServer3D.get_debug_navigation_edge_connections_material()
  • same
• ED_SHORTCUT()
  • easiest way to create configurable keyboard shortcuts in the editor
  • not currently possible: https://github.com/godotengine/godot-proposals/issues/2024
• InputEventKey::create_reference()
  • significantly reduces the amount of code needed to create ED_SHORTCUT() work-alike by hand
• PhysicsMaterial.computed_friction() & PhysicsMaterial.computed_bounce()
  • relatively simple to reproduce, but doing so assumes the internals will never change
