  [flang] Fold NORM2() (#66240)

Fold references to the (relatively new) intrinsic function NORM2 at
compilation time when the argument(s) are all constants. (Getting this
done right involved some changes to the API of the accumulator function
objects used by the DoReduction<> template, which rippled through some
other reduction function folding code.)
