Olivier 'reivilibre 16fe5fb462 Expose MSC4354 Sticky Events over MSC4186 (Simplified) Sliding Sync. (#19591) ...

Follows: #19487
Part of: MSC4354 whose experimental feature tracking issue is #19409

This PR implements the Sliding Sync (MSC4186) extension described in
MSC4354, allowing sliding sync clients
to receive sticky events in a reliable way.

The logic is much the same as for oldschool sync (implementation in
#19487),
although in the sliding sync extension, the client can choose their own
limit
and must control their own pagination through an extra token in the
extension request/response bodies.

Note this does not yet send down existing sticky events in the
room when the room has been newly-joined.
This newly-discovered gap is tracked at #19662 and will be addressed for
both current sync and MSC4186 SSS soon.
