[flang][OpenMP] Map simple `do concurrent` loops to OpenMP host constructs (#127633)

Upstreams one more part of the ROCm `do concurrent` to OpenMP mapping
pass. This PR add support for converting simple loops to the equivalent
OpenMP constructs on the host: `omp parallel do`. Towards that end, we
have to collect more information about loop nests for which we add new
utils in the `looputils` name space.
