Document some structures in attribute_stats.c

Browse Source 
Like relation_stats.c, these structures are used to track the argument
number, names and types of pg_restore_attribute_stats() and
pg_clear_attribute_stats().

Extracted from a larger patch by the same author, reworded by me for
consistency with relation_stats.c.
