Room header UI updates (#11507)

* Fix performance issues with useRoomMembers

With the current implementation it would create a new function, with leading: true, rendering the whole throttling useless

* Add public room indicator

* Format room members count better

* Add public room test

* Add search to room summary card

* Update settings UI

* Update snapshot

* Remove default title attribute
