code: def create_npu_function_pass(opt_level: int, name: str = ""):
      """
      A utility decorator that wraps a given class as an NPU function pass. That is,
      a pass that behaves like a function pass and only traverses NPU external
      functions. How each NPU function is mutated is defined by the
      `transform_npu_function(global_variable, relay_function)` function which should
      be created in the class that is to be decorated. See the example below.
  
      Example
      -------
      This small example demonstrates a pass over NPU functions that performs no
      mutation.
  
      @create_npu_function_pass(opt_level=1)
      class MyPass:
          def transform_npu_function(self, global_var, func):
              return func
  
      mod = tvm.IRModule()
      mod = MyPass()(mod)
  
      Parameters
      ----------
      opt_level: int
          Optimization level for the module pass.
      name: str, optional
          Name for the module pass.
  
      Returns
      -------
      decorator
          The npu_pass decorator.
