Add an option to MarkAccumulator to let it generate markup that includes live shadow DOM tree. To ensure the shadow
DOM tree is correctly interpreted as shadow DOM in generated markup string, we wrap it with a template element string.

API test: WebArchive.SaveResourcesShadowDOM
          WebArchive.SaveResourcesDeclarativeShadowDOM
