Only iterate through raw contact delta list once (E3)

* Also, don't treat emails and phone numbers differently
  since we'll be adding a new KindSectionView for them.
* Introduced a multi account aware KindSectionData holder
  object to be used by the new KindSectionView
* Moved the utility method to get the icon for each kind
  from the exisitng KindSectionView to EditorUiUtils
