The drill-thru is mostly a stub to put an entry in the context menu. Most of the logic for this is built on the FE using the existing functions for consuming and creating expressions.

See [thread](https://metaboat.slack.com/archives/C06P22KS4JH/p1712264174056569) for a lot more context.

This also adds `docs/developer-guide/mbql-library-changelog.md` and documents adding this function to the library as the first change in the API. I'll follow up in another PR with Github automation to expect the changelog to be updated whenever `src/metabase/lib/js.cljs` changes.

Fixes #39978.
