Consistently avoid close() call on Servlet OutputStream [SPR-11413]

[spring-projects-issues]

Juergen Hoeller opened SPR-11413 and commented

Next to MarshallingView (#16038), ResourceHttpRequestHandler and ShallowEtagHeaderFilter should not delegate to FileCopyUtils (which calls close() on the OutputStream) but rather to StreamUtils, leaving a chance for outer filters to add to the response still.
