Follow up to #16338, modifies the logic to only consider
STRINGtype columns as dictionary encoded instead of anything withColumnCapabilities.isDictionaryEncodedset to true. This was a problem because currentlyVectorColumnSelectorFactorycan only make dictionary encoded selectors forSTRINGtyped columns, so any other type that is non-numeric but dictionary encoded cannot currently take advantage of this functionality.
