Control panel expanded state via blueprint APIs

[jleibs]

What

These replace the old python_bridge APIs.

Also plumb through some missing components:

• Viewport.auto_space_view
• Viewport.auto_layout
• SpaceView.display_name

Updated the old python blueprint example now that the bridge APIs are gone.

Example code:

        blueprint = Blueprint(
            Viewport(
                Grid(
                    Spatial2D(name="Rect 0", origin="/", contents=["image", "rect/0"]),
                    Spatial2D(name="Rect 1", origin="/", contents=["image", "rect/1"]),
                ),
                auto_space_views=args.auto_space_views,
            ),
            BlueprintPanel(expanded=False),
            SelectionPanel(expanded=False),
            TimePanel(expanded=False),
        )
