User verification state indicators (#3793)

* Introduce a `UserIdentityProxy` and have it combine upstream methods into an easy to digest  `UserIdentityVerificationState`. Use it in a dedicated `VerificationBadge` UI component

* Show a DMs counterpart verification state in the room header

* Show a warning on the room details `People` entry when there are identity verification state violations on any of the members.

* Show verification badges in the room member list

* Show a withdraw verification section on the room member details for users that have pinning violations.

* Remove the verification section from the profile screen as there's no reliable way to keep it up to date
- the underlying Rust SDK Olm Machine can be rebuilt without notice which would break any existing user identity change streams.

* Update preview test snapshots
