Paul ChobertandQuentin Gliech ab8f060746 Deliver Server Announcement over Legacy Sync (#20412)
> [!NOTE]
> **Epic**: [Efficient Server
Announcements](https://github.com/element-hq/synapse/issues/20240)
> Follows: https://github.com/element-hq/synapse/pull/20372

When a new announcement is sent in the announcement room, this PR will
ensure that the announcement and the room state are shared with the
client over Legacy Sync.

If you reviewed the PoC before, please note that there are several
differences:
- We intentionally don't wake all sync
- We don't want typing and receipts
- We don't need device lists
