[geo] introduce "Auto Zoom" control (#4389)

* [geo] introduce "Auto Zoom" control

On geospatial visualization, checking the "Auto Zoom" control makes it
such that the viewport is fitted to the data upon rendering the chart.

For dashboards with region filters, the map should jump to the right
position.

Eventually we should enhance this to fly and ease to the position in an
animated way.
