Render config templates with a tree walk (#5186)

--generate_config post-processed the library writer's output line by
line and --update_config aligned two such outputs line by line, which
asserted and produced garbage as soon as the two documents differed in
shape, for example when the file set peering_port and the defaults did
not. A small renderer in config_template now walks the table, writes
headers and doc comments itself and comments a value out on request;
the update variant compares each value with its default. The output of
--generate_config is unchanged byte for byte. The diff and merge
helpers leave tomlconfig along with the erase_default_values tooling
that nothing used.
