misc (matrix) : use innerClient.subscribeToRoomInfo sdk method

[ganfra]

Content

Rework how we manage the client.roomInfoFlow by using the new innerClient.subscribeToRoomInfo sdk method.
Ensure we are using only RoomInfo and not RoomSummary as those ones are bound to the RoomList.

Motivation and context

Makes sure we can observe RoomInfo for any room, either a known or unknown room, no matter the filter applied to the room list.
