      Creates a cache key that is a hex-encoded string of a unique hash based on
      the arguments. The hex-encoded string is 256 characters long.
  
      Args:
        module: the input program
        devices: an array of accelerator devices that the program will run on
        compile_options: options passed to the XLA compiler
        backend: description of the platform (e.g., TPU version)
        compression_algorithm: a string representing the compression algorithm used
