Replace Matrix.getKeyBackupEnabled by `MatrixClient.CryptoApi.getAc…

…tiveSessionBackupVersion` (#28225) * Migrating deprecated sync `MatrixClient.getKeyBackupEnabled` to async `MatrixClient.CryptoApi.getActiveSessionBackupVersion` in `NewRecoveryMethodDialog`. Rewrite `NewRecoveryMethodDialog` into a functional component to make it easier to handle the new async method. * Migrating deprecated sync `MatrixClient.getKeyBackupEnabled` to async `MatrixClient.CryptoApi.getActiveSessionBackupVersion` in `MatrixChat`.
