Deprecation: #62800 - Workspaces ToolbarItem via ExtDirect

See forge#62800

Description

The PHP functionality for switching a workspace was done with the ExtDirect call TYPO3.Ajax.ExtDirect.ToolbarMenu until now. This has been replaced by a simple AJAX JSON call, based on jQuery and the refactored ToolbarItem Menu for the workspaces module.

Impact

The core does not use this functionality anymore, and also removed the ExtDirect registration for this class.

Affected installations

All installations which directly used the ExtDirect TYPO3.Ajax.ExtDirect.ToolbarMenu to fetch the data.

Migration

Use the new AjaxHandler Workspaces::setWorkspace() directly instead.
