app_list: Add search box and search result view for v2.

- Add a SearchBoxModel that represents search box's icon, placeholder text,
  user typed text and selection model (current selection and cursor position);
- Add a SearchBoxView that displays SearchBoxModel and observes SearchBoxModel
  changes via SearchBoxModelObserver;
  When user typed/changed text in search box, the view also fires query changed
  notification to its SearchBoxViewDelegate;
- Add a SearchResult that carries an icon, two tagged texts;
- Add a SearchResultView that displays a SearchResult;
- Change AppListModel to be a master model that has three sub models:
  apps list, search box and search results;
- Add a SearchResultListView that display search results sub model of
  AppListModel using a list of SeachResultView;
  The view supports up/down key navigation and when user selects a result
  via mouse click or enter key, it asks its SearchResultListViewDelegate to
  OpenResult;
- Update AppListViewDelegate:
  - Add new methods: StartSearch, StopSearch and OpenResult;
  - Deleted no-longer needed UpdateModel method;
  - Rename OnAppListItemActivated -> ActivateAppListItem;
- Update ash_shell's app_list to support a simple substr match search;
- Add a SearchBuilder that implements the search via AutoCompleteController;
- Other changes:
  - Rename AppListModelBuilder -> AppsModelBuilder;
  - Rename AppListModelView -> AppsGridView;

BUG=125964
TEST=Manual. In ash_shell, it searches the 5 example apps. In ash/chrome, it should show similar results as omnibox.
