Causing Mac build failures

> Refactor views app list services to allow more code sharing

> To run the toolkit-views app launcher on Mac, it needs a new app list

> It does this principally by:
> - Moving `app_list_shower` to `app_list_shower_views`, making it views-specific;
> - Adding AppListServiceViews, which Win/Linux (and soon Mac) inherit from;
> - Rearranging the delegation to eliminate some boilerplate.
>
> Other changes:
> - Removed AppList container abstract interface (now just access AppListView);
> - Removed AppListFactory (now AppListShower::MakeViewForCurrentProfile());
> - Moved AppListControllerDelegateLinux to AppListControllerDelegateViews;
> - Most of AppListServiceLinux moves to AppListServiceViews;
> - Added AppListShowerDelegate and AppListShower given virtual method
> hooks to assist testability (previously AppListShower was given a NULL
> service/delegate in tests);
> - Positioning logic in AppListWin/AppListLinux made static/stateless;
> - Removes the `on_should_dismiss_` closure (now just dismiss via the service;
> - Big trim of AppListServiceWin and AppListServiceLinux - now these are
> just platform-specific stuff.
