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.
