coolwsd.xml defaults vs. built-in defaults

[timar]

Describe the Bug

In #10049 it was requested that coolwsd.xml defaults should match built-in defaults, and some progress was made. Now we have a systematic approach.
coolwsd logs non-default values from coolwsd.xml at startup.

For example:
podman run -i -t --name collabora_code -p 9980:9980 -e "extra_params=--o:ssl.enable=false --o:ssl.termination=false" docker.io/collabora/code:latest

• Here only the ssl.enable: false is interesting, because we changed that one in the command line.
• The empty values may be empty in coolwsd.xml but have a default in the code so that default prevails.
• When there is a value, probably it's defined in coolwsd.xml, but not in the code. This is what coolwsd.xml defaults do not match built-in defaults #10049 was about originally.
• Ideally we should only see what is relevant, in this list.

(I just dumped it so I do not forget, nothing is urgent about it. It was CODE 24.04.10.1.)
