* Check native sliding sync support against an unstable feature flag
The `OPTIONS` approach from https://github.com/matrix-org/matrix-react-sdk/pull/12492 doesn't work because Synapse *always* responds with 204 (success) to `OPTIONS` requests, as described here: https://github.com/element-hq/synapse/issues/17153
We further can't use `HEAD` because it's not part of the allowed CORS methods, meaning the browser will mask the exact status code and error message from us, and the proxy hangs on the request anyways: https://github.com/matrix-org/sliding-sync/pull/429
To avoid these problems, we instead search for an unstable feature flag to be exposed by the server. Presence of this flag denotes native support. See https://github.com/matrix-org/matrix-spec-proposals/pull/3575/files#r1588877046 for details.
Implementations which support sliding sync natively will need to update to support this new unstable feature flag usage.
* Appease the linter
* Appease the tests
* Use OPTIONS for sliding sync detection poke
This avoids unintended consequences, including high resource usage, which would accompany a "full" sync request. Instead, we just grab headers and enough information for CORS to pass, revealing likely support.
Fixes https://github.com/element-hq/element-web/issues/27426

* sliding-sync: spider all rooms on the user's account for search
On startup, slowly accumulate room metadata for all rooms on the
user's account. This is so we can populate the local search cache
with enough data for it to function, obviating the need to have
separate code paths for sliding sync searches.
This will allow spotlight search to work with slow/no network
connectivity, though clicking on the room will still require a
round trip.
This is an explicit request from @ara4n to improve the snapiness
of room searches, despite the unbounded bandwidth costs requesting
all N rooms on the user's account.
* Comments and tweak defaults
* Review comments; remove SS search code
* bugfix: use setListRanges once the list has been set up
If we don't, then we send needless extra data and can cause
bugs because setList will wipe the index->room_id map, which
trips up SlidingRoomListStore.
