Feature: #96152 - Backend Toolbar items overview in configuration module

See forge#96152


With forge#96041, the registration of backend toolbar items had been improved. Instead of being registered via $GLOBALS, all implementations of TYPO3\CMS\Backend\Toolbar\ToolbarItemInterface are now automatically registered, while taking the defined index into account.

To still allow administrators an overview of the registered toolbar items, especially the final ordering, a corresponding list has been added to the configuration module.


It's now possible for administrators to get an overview of all registered toolbar items and the final ordering in the Configuration module.
