easy enough for users to customize them manually if they want to.

Drop support for the dead third-party w3 package

The w3 package was removed from GNU ELPA in 2020 as it doesn't run on
a recent Emacs, and development had stopped over a decade before that.
If anyone wants to revive the w3 package, they should look this all
over, but it doesn't make sense for us to maintain this support code.
