Sliding Sync: Make sure we get up-to-date information from get_sliding_sync_rooms_for_user(...) (#17692)
We need to bust the `get_sliding_sync_rooms_for_user` cache when the room encryption is updated and any other field that is used in the query. Follow-up to https://github.com/element-hq/synapse/pull/17630 - Bust cache for membership change (cross-reference `get_rooms_for_user`) - Bust cache for room `encryption` (cross-reference `get_room_encryption`) - Bust cache for `forgotten` (cross-reference `did_forget`/`get_forgotten_rooms_for_user`)
