Highlight feature for ui5-li/ui5-suggestion-item

[allen138]

1. When using the ui5-input as a search input, the character typed in the search field should be highlighted/bold in the search results. It would be great if a property can be added to have this as an optional feature.
2. The following screen shot shows the anticipated behavior. User types "adm" and the suggested item looks like "Administrative Support"
   

Thanks,
