function visitNodeWrapper(oElement, oInterface) {
		return oInterface.visitNode(oElement);
	}
Wrapper for the "visitNode" function which is sometimes returned by
{@link sap.ui.core.util.XMLPreprocessor.plugIn}. Delegates to the appropriate "visitNode"
function from the callback interface (which is not yet available at plug-in time) and makes
sure no extra arguments are passed.

@param {Element} oElement
  The XML DOM Element
@param {sap.ui.core.util.XMLPreprocessor.ICallback} oInterface
  The callback interface
@returns {sap.ui.base.SyncPromise}
  A thenable which resolves with <code>undefined</code> as soon as visiting is done, or is
  rejected with a corresponding error if visiting fails (since 1.57.0)
