Deprecate Attr.nodeValue / Attr.textContent

LayoutTests/resources/dump-as-markup.js

 /**
  * There are three basic use cases of dumpAsMarkup
  *
  * 1. Dump the entire DOM when the page is loaded
  *    When this script is included but no method of Markup is called,
  *    it dumps the DOM of each frame loaded.
  *
  * 2. Dump the content of a specific element when the page is loaded
  *    When Markup.setNodeToDump is called with some element or the id of some element,
  *    it dumps the content of the specified element as supposed to the entire DOM tree.
