Support chart type selection from within the Row Col Chart component

[Brian Lewis]

Take the buttons in Chart Manipulation component that allow selection of the chart type, and move this inside the Row Col Chart component.

When supplied, the binding allowedTypes is the types of chart that the user can select in the rowcol chart instance… these are displayed on a popout ribbon. If allowedTypes is not set, this ribbon is not available.

With this in place, the user could have the flexibility to choose between different chart formats wherever this component is used on any dashboard. Combined with the ability to then download the chart image as a .png, this would give the user a powerful tool for creating charts that could be immediately inserted into reports, or other static contexts.

Note this is related to #830, since the chart type icons would then be needed by the Row Col chart component.
