logging all CICE6 parameters

splitting https://github.com/COSIMA/access-om3/issues/117#issuecomment-2021818399 off as a separate issue

MOM6 outputs all parameters into MOM_parameter_doc.* files, which is very useful for documentation - see https://github.com/COSIMA/access-om3/issues/117

It would be great if we could do something equivalent for CICE6. archive/output000/log/ice.log apparently reports all parameter values, but interspersed with irrelevant text. It would be more useful if this was output separately, ideally as a complete, valid namelist of all runtime parameters.

Thoughts, anyone?

It looks likes there are few main sections where this is written:

• spew in ice_init
• domain information in ice_domain
• history output in ice_history
• ice_init_column & part 2

Plus some in icepack

It probably wouldn't be too hard to make a patch to write these to a different file? Otherwise, we could probably get most of the information through some clever scripting.

Some of the icepack sections maybe are less relevant and there is a little bit of repetition but with a little iteration we could maybe tidy this up.

Thanks @anton, it seems cleaner to me (and maybe less work?) to patch cice to write this to a separate file, ideally as a valid namelist file readable by f90nml.
