69871825 - [flang][OpenMP] `do concurrent`: support `reduce` on device

[flang][OpenMP] `do concurrent`: support `reduce` on device Extends `do concurrent` to OpenMP device mapping by adding support for mapping `reduce` specifiers to omp `reduction` clauses. The changes attach 2 `reduction` clauses to the mapped OpenMP construct: one on the `teams` part of the construct and one on the `wloop` part.
