  [MLIR][NVVM] Update redux.sync op (#166125)

This change:
- Updates the `redux.sync` NVVM Op input and output type constraints.
- Adds a verifier for the Op to prevent stack dumps and hitting
  `llvm_unreachable` in certain invalid usage scenarios.
  Instead, we gracefully error out with an informative
  message now.
