My initial gut reaction was that we should just rely on what per_connection_state.receipts says for whether something is an initial room. But I think it makes to try to match the timeline with receipts when all of those timeline messages are available. We should add a comment about why we care to do this.

Since this interacts with initial: true, we should also maybe note that there are going to be weird interactions if people enable/disable the receipts extension during the lifetime of the connection. For example, if they have the receipts extension disabled at first and then enable it later; they'll get the initial: true chunk of timeline but no receipts, and then on incremental sync when the receipts extension is enabled, there won't be many/any timeline events so all of the receipts will be filtered out.

Should we use this helper for the rest of the receipts tests?

Yup, we should, just didn't want to inflate the PR

This supersedes #17503, given the per-connection state is being heavily
rewritten it felt easier to recreate the PR on top of that work.

This correctly handles the case of timeline limits going up and down.

This does not handle changes in `required_state`, but that can be done
as a separate PR.

Based on #17575.
