Eliminate duplicate Layout DOM wrappers

Browse source 
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.
