Extracting isScopeSelected action from FilterChip

Created by: christinaforney

Move selected state computation up a layer to the SearchResultsFilterBars and SearchFilterChips. This is necessary as we move in a direction that brings search options out of the search bar, and captures them in the filters section as selected or de-selected toggles. Ultimately extracting the selected filters from the search query will be done up-front, rather that checking if a filter is in the query.
