Eric Eastwood 6100f6e4f7 Backfill from nearby points past pagination token (#19611) ...

The juicy details and explanation are in the diff itself.

Split out from https://github.com/element-hq/synapse/pull/18873 in order
to fix paginating from
[MSC3871](https://github.com/matrix-org/matrix-spec-proposals/pull/3871)
gap tokens actually backfilling history. To be clear, this is a good
change to make outside of the
[MSC3871](https://github.com/matrix-org/matrix-spec-proposals/pull/3871)
use case. For example (as the new Complement test shows), fixes a
problem where if you try to paginate `/messages` from tokens returned by
`/context`, we could fail to backfill anything new and hide away
history.
