docs: Declares that this builder should minimize system-level output
  (Ion version markers and local symbol tables).

  This is equivalent to:
  <ul>

  setInitialIvmHandling}{@code (}{@link IonWriterBuilder.InitialIvmHandling#SUPPRESS SUPPRESS}{@code )}
  <li>{@link #setIvmMinimizing(IonWriterBuilder.IvmMinimizing)

  </ul>
  
  @return this instance, if mutable;
  otherwise a mutable copy of this instance.
