* Replace `MatrixClient.isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `Searching.ts`

* Replace `MatrixClient.isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `SlidingSyncManager.ts`

* Replace `MatrixClient.isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `EncryptionEvent.tsx`

* Replace `MatrixClient.isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `ReportEventDialog.tsx`

* Replace `MatrixClient.isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `RoomNotifications.tsx`

* Fix MessagePanel-test.tsx

* ReplaceReplace `MatrixCient..isRoomEncrypted` by `MatrixClient.CryptoApi.isEncryptionEnabledInRoom` in `shouldSkipSetupEncryption.ts`

* Add missing `await`

* Use `Promise.any` instead of `asyncSome`

* Add `asyncSomeParallel`

* Use `asyncSomeParallel` instead of  `asyncSome`
