VTKVolume: Toggle option for dropdown UI in image

[JeffreyWardman]

Problem: Dropdown UI widget (represented by the VTKjs favicon logo) in image is on by default, covering the image (easily reproducible with pn.Row(image, image, image)).

Solution: Option to turn on/off the widget (with off being the default setting)

Additional: Would be useful to customize the dropdown UI widget itself as well.

Implemented in #1631

Happy to keep this open, if you have concrete suggestions on customizing the UI. Also worth noting that #1631 did not set the default to off.

@philippjfr Keeping this closed is fine. I think it's bad UX to have it open by default. When the image/window is small, the UI covers a large part of the object (the brain in #1631). For instance, a row consisting of the tabs, and three of these brain images results in a frustrating experience.
