Show segment hash in segmenteditor.getAll output to aid debugging. #16989

Description:

In case a user does not want to reveal a segment due to it having sensitive information, it can be hard to figure out exactly what the hash for a segment is (especially when there is an encoding or related problem). So adding it to the API output can be useful for debugging.
