> views: change WrenchMenu to use each model's command ID's when creating MenuItemView's
> 
> this is in preparation for dynamic recent tabs model and menu:
> 
> * WrenchMenu:
> - for each menu item, MenuItemView::GetCommand() used to be separate and different from MenuModel::GetCommandIdAt(model_index); they are the same now.
> - different range of command id's are reserved for recent tabs and bookmarks.
> - command id's of all items in the wrench menu and all its submenus can't clash, except for separator and IDC_SHOW_HISTORY, the latter of which is in both wrench menu and recent tabs submenu.
> 
> * RecentTabsSubMenuModel:
> - make all command ids within range, use different ids among device name headers.
> 
> BUG=256750
> TEST=wrench menu and all its submenus still work.
