2b8c1178 - [MLIR][NVVM] Remove the `nvvm.barrier0` op (#195608)

[MLIR][NVVM] Remove the `nvvm.barrier0` op (#195608) This PR removes `nvvm.barrier0` because it is a duplicate op. `nvvm.barrier` can cover its functionality and more. `nvvm.barrier0` was added historically. It is confusing to maintain it right now.
