Add profile selector menu to app list.

Adding a profile selector in the app list menu because currently the only way
to switch the profile is to go into the app list settings which is hard to
find. This CL covers both the mac and windows app list.

The app list switches the profile in place without respawning the app list.

* Added AppListModel::User struct to represent a User in the app list.
* Added a vector of Users to AppListModel.
* AppListMenu builds it model with respect to AppListModel::Users.
* The AppListViewDelegate profile is now switchable via SetProfilePath(). Calling this rebuilds the AppListModel which notifies the view to update.
* Removed custom menu items and views from app_list_menu_views.cc and deleted current_user_menu_item_view on mac.
* Changed ui assets that indicate the current user of the app list.
* Tweaked PaginationModel to handle an app list with 0 apps.
* Mac app list now sets a new delegate to switch the app list profile rather than
dismissing and reshowing.
