Force last owner of a room to pass ownership when leaving (#5094)

Browse source 
* Move `ChangeRoles*` classes to their own module so they can be shared

* Hook the change roles screen to the leave room action, add confirmation dialogs

* Use enum instead of sealed interface for `ChangeRoomMemberRolesListType`

* Try to improve communications between nodes

* refactor (leave room) : makes sure to expose only necessary code from api module

* Add `:libraries:previewutils` module to share some test fixtures used for UI previews

* Update screenshots
