  [flang][openacc] Use bounds information in reduction recipe combiner (#67719)

This patch makes use of the bounds in the combiner region for known
shape arrays. Until know the combiner region was iterating over the
whole array.
Lowerbound, upperbound and step are passed as block arguments after the
two values.

A follow up patch will make use of this information for the assumed
shape arrays as well.
