The auto-generated header and configuration files in the test/format directory sometimes get out of sync with the human-generated declarations in test/format/config.sh.

One example is WT-15017, where we made a change to the config but forgot to run the script. That resulted in the aforementioned files being out of sync on develop for multiple weeks.

We got really lucky here – the mismatched files didn't seem to cause any issues, but it could easily have been different.

We already have s_all to check the WT API config, and it wouldn't be hard to extend that to test/format, so let's do it.
