Update SQL features count
The previously listed total of 179 does not appear to be correct for
SQL:2016 anymore. (Previous SQL versions had slightly different
feature sets, so it's plausible that it was once correct.) The
currently correct count is the number of rows in the respective tables
in appendix F in SQL parts 2 and 11, minus 2 features that are listed
twice. Thus the correct count is currently 177. This also matches
the number of Core entries the built documentation currently shows, so
it's internally consistent.
