-Werror=dangling-reference

"c++: Implement -Wdangling-reference [PR106393]" grew a new warning, included in
-Wall, and based on some more-or-less shaky heuristics, that warns about
"possibly dangling reference to a temporary".  It produces quite a number of
false positives, but for these uses of SfxItemSet::Get it does look plausible
that the returned item references could, at least in theory, point at data that
is destroyed along with the temporary SfxItemSet.
