feat(WidgetDriver): Send state from state sync and not from timeline to widget

[toger5]

This PR changes the source of messages send to the widget. Instead of using:
let handle = self.room.add_event_handler(move |raw: Raw<AnySyncTimelineEvent>| {})
which listens to all events form the timeline section of the sync, we use two listeners for state and message like:
let handle = self.room.add_event_handler(move |raw: Raw<AnySyncStateEvent>| {})
And
let handle = self.room.add_event_handler(move |raw: Raw<AnySyncMessageLikeEvent>| {})

AnySyncStateEvent should only get events from the state block of the SSS response.
and AnySyncMessageLikeEvent all the message like events from the timeline block.

This makes the behaviour equivalent to: element-hq/element-web#28422

• Public API changes documented in changelogs (optional)

lgtm 👍

@stefanceriu @bnjbvr, I asked this in one of the room but it does not hurt to ask for double confirmation that this comment is actually what is happening:

// Get only all state events from the state section of the sync.
let handle_state = self.room.add_event_handler(move |raw: Raw<AnySyncStateEvent>| {
    let _ = tx.send(attach_room_id(raw.cast_ref(), &room_id));
    async {}
});

Looks like that to me, yes:

matrix-rust-sdk/crates/matrix-sdk/src/event_handler/mod.rs

Line 351 in ee7c80c

state_events: &[Raw<AnySyncStateEvent>],

Confirmed with @bnjbvr that this is indeed correct, will go ahead and merge it 👍
