[Mlir-commits] [mlir] [mlir][shard, mpi][NFC] Add missing header (PR #179777)

[Jordan Rupprecht]

https://github.com/rupprecht created https://github.com/llvm/llvm-project/pull/179777

Utils.h uses `mlir::mpi::CommWorldOp` w/o including the necessary header (https://llvm.org/docs/CodingStandards.html#self-contained-headers), making this not self contained. It only works because all the .cpp files that use it have the necessary include.
