There are duplicate sets of Layout DOM wrappers: one for Layout 2013 and one for Layout 2020. As part of cleaning up and simplifying the wrappers, this change parameterizes them on the specific layout data they contain. This allows them to be shared again. In addition, various small cleanups are included. Fixes #29691.
