optimize ScColumns::HasCellNotes()

This probably doesn't matter much for optimized code, but in dbgutil
builds this avoids all the libstdc++ iterators mutex locking (WTH
does libstdc++ debug mode need to lock anything?). It's functionally
equivalent (similarly to ScColumn::IsEmptyData(), and the container
can contain only notes or empty elements), and cuts run time of e.g.
sc_uicalc test to about a half.
