Add missing include for DOMNode.hpp to MiscalibReaderFromXMLDomUtils.h

[Teemperor]

The MiscalibReaderFromXMLDomUtils.icc file we include in this file
tries to access the getNodeValue() method of a DOMNode, so we also
need to include the related header to make this header compile
on it's own.

[Teemperor]

Part of the work going on regarding the C++ modules migration of CMSSW (tracked as issue #15248). This PR is not meant to refactor things, but just to make these headers compile.
