  [flang] `do concurrent`: fix reduction symbol resolution when mapping to OpenMP

Fixes 155273

This PR introduces 2 changes:
1. The `do concurrent` to OpenMP pass is now a module pass rather than a
   function pass.
2. Reduction ops are looked up in the parent module before being
   created.

The benefit of using a module pass is that the same reduction operation
can be used across multiple functions if the reduction type matches.
