Derived from #92480. This PR supports parsing of the DO CONCURRENT REDUCE clause in Fortran 2023. Following the style of the OpenMP parser in MLIR, the front end accepts both arbitrary operations and procedures for the REDUCE clause. But later Semantics can notify type errors and resolve procedure names.
