[ENG-9603](https://linear.app/comm/issue/ENG-9603/make-it-possible-to-sign-message-with-olm-account-from-user-keys). Needed to sign new device list with old primary device account. This doesn't need to be scheduled on `cryptoThread` because it is using ephemeral `CryptoModule` but perhaps it's better to keep similar to all crypto-related operations and use dedicated thread. Depends on D14045
