Prior to this, if Synapse was upgraded from a sufficiently old version foreground migrations touching the stream_ordering column of the events table would apply before a background job also touching the same column was finished, resulting in the background job failing. Fixes #15677.

This work supercedes #15724, which turned out to be unworkable.

Hmm, I'm not seeing anywhere in the code where we actually validate these constraits?

I don't think that has happened yet. These columns/constraints were introduced in #15356. On the discussion of that PR there is mention of validating them in the future, after a background job migrates historical data from the stream_ordering column of events to the new stream ordering columns added, but I don't see anywhere in the deltas after this (for reference these were added in 74) that the background job was added and run or that the constraints were validated.
