Add test checking driver defmultis are mentioned in changelog (#32262)

* Add `:added` metadata to driver multimethods

Commit which introduced defmulti was determined
with `git log -L<line>,+1:<file>. Then first version it appeared in
was extracted from `git tag --contains <sha>`.

* Add driver methods changelog test

* Add `:changelog-test/ignore` to various defmultis

Multiple defmultis added after 42 incl. are missing entries from
changelog. Marking them this way makes it possible to add those
entries retrospectively without having failing tests, one by one.
