Show id and title of linked processes in metadata editor

[solth]

Currently only the document type of linked processes is displayed in the metadata editor. That can become quite confusing and does not help a lot when multiple child processes of the same type are linked to one parent process, because it is not obvious which child node in the structure tree represents which child process, and thus, the order of those child processes (and potential pages in the parent process) cannot be validated/checked:

The change in this pull request displays additional information about the linked processes, namely it's ID and process title, similar to what is displayed in when linking title records during metadata import.
This helps identifying specific child processes and structuring linked processes and pages within a parent process:

Thanks a lot, that is a really good improvement!

Maybe it could also be regarded, that the position of an issue might need be corrected, if the order is not correct.

@andre-hohmann I think that will be possible after #4850 is merged!
