docs: Creates a GRR VFS temp file.
  
    This function is analogous to CreateGRRTempFile but returns an open VFS handle
    to the newly created file. Arguments are the same as for CreateGRRTempFile:
  
    Args:
      filename: The name of the file to use. Note that setting both filename and
         directory name is not allowed.
  
      lifetime: time in seconds before we should delete this tempfile.
  
      mode: The mode to open the file.
  
      suffix: optional suffix to use for the temp file
  
    Returns:
      An open file handle to the new file and the corresponding pathspec.
