[MLIR][Transform] Fix PrintOp::build with StringRef

[JoeyYe_HW]

Summary

transform::PrintOp::build(OpBuilder &builder, OperationState &result, StringRef name) does not set name correctly. Calling PrintOp::build(builder, result, "whatever name") is going to end up with a PrintOp with no name.

This patch fixes it by replicating the approach from tablegen created code. Refer to build/mlir/include/mlir/Dialect/Transform/IR/TransformOps.cpp.inc

mlir/lib/Dialect/Transform/IR/TransformOps.cpp
