We can already re-use the data from sort_rooms(...) and return a _SortedRoomMembershipForUser(...) that includes the stream_ordering of the latest event in the room which we can compare to our from_token. See b59ccf7 for how I previously did this for sharing the bump_stamp info.
Then when the sliding sync tables land, we can use them in sort_rooms() to make that faster.
We can also do this in a follow-up since the PR is already nice and compact to introduce the concept 🤷

Ah yeah, I was thinking that we should reuse some of the work from the work you were doing with the DB tables, but forgot we could already reuse what we had from sort_rooms. I might leave this as is for now until we land the new DB tables? That way we don't collide, and we can land this PR ASAP
