New visualization UI API

[kazcw]

Pull Request Description

• Improve visualization UI APIs:
  • Isolate visualizations within a Vue Custom Element to prevent any unintended interaction between GUI and visualization CSS/JS.
  • New visualization-menus API: Visualizations no longer create toolbars using the GUI's components; a simpler JS interface moves the responsibility for appearance of controls to the GUI.
  • Simplify visualization configuration interface. Properties that should not be exposed to visualizations have been removed. Visualizations no longer need logic implementing fullscreen mode; the size property reflects the current renderable area.
  • Visualizations no longer use a VisualizationContainer; the visualization simply renders its content at its root.
• Viz dropdowns: Buttons always show arrows (fixes Add dropdown indicator arrows to the table Viz menu buttons #10809)
• Fullscreen mode: Fix rendering size of scatter plot and other visualizations
• JSON visualization interactivity: Fix intermittent incorrectly non-interactive state
• Viz toolbars: Fix squished-looking rightmost button.

Other API changes:

• Interaction no longer includes GraphNavigator with pointer events.

@Frizi The other side of viz API improvement is the static-API change we talked about, but I think that change will mostly affect different code from this, so let's merge this separately since it contains API changes and several bugfixes.

Probably don't need the inner div anymore.
