[TASK] Remove doubled classes in EXT:version

The AutoPublishTask and the WorkspacesUtility are actually
very encapsulated and never used nor registered in EXT:version.

Instead, EXT:workspaces provides EXACTLY the same functionality,
and the scheduler task there is registered.

Looking back in history, I did not find any functionality where this
was actually used, so the files are removed.

A class alias map is added to provide ultra-compatibility without
any breaking changes nor deprecations.
