Add a setting to the dataframe view for indicator/empty/clear column default visibility

[abey79]

#7677 introduced a mechanism to exclude indicator component, empty columns, and/or Clear component from the view. By default, all of these are now excluded in the dataframe view. We should have a setting to control this behaviour, if only for educational purposes (actually seeing these columns is rarely useful).

Challenge: our current story to reflect the view content and selection in the UI is not great. Adding this toggle can potentially worsen the situation, so we need a careful design around this.
