Use special XContent registry for node tool (#54050)
Fixes an issue where the elasticsearch-node command-line tools would not work correctly because PersistentTasksCustomMetaData contains named XContent from plugins. This PR makes it so that the parsing for all custom metadata is skipped, even if the core system would know how to handle it. Closes #53549
