Update to suggestions list

[thaddmt]

Overview

• Set showResultMarkers to true by default
• Change suggestions library to suggestions-list
  • suggestions-list forks suggestions to add feature support for not selecting any list items by default
• Update geocoder enter keypress behavior
  • Previously would set the list value to the selected item and redo search API call with that input
  • Now in the geocoder it will check if a list item is active
    • If list item is active then geocoder will not call search API and will list the suggestions-list set the value and hide list results
    • If there is no list item active it will do a geocoder search API call
