Added Rococo BH <> Rococo Bulletin bridge (paritytech#2724)

* added Rococo BH <> Rococo Bulletin bridge * init-bridge support * allow customising finality-related runtime APIs * revert me * use Rococo/BridgeHubRococo pretending to be a Polkadot/BridgeHubPolkadot in Rococo <> RococoBulletin bridge * Revert "revert me" This reverts commit 90c598d9d50a25e7182c97eee7818bf8d4bc404c. * Revert "allow customising finality-related runtime APIs" This reverts commit b39c32c34acddfd0b919042122e0e667470bd0a4. * fmt * WITH_BRIDGE_ROCOCO_TO_BULLETIN_MESSAGES_PALLET_INDEX * regenerate bulletin chain runtime (pallet indices have changed) * fx WITH_BRIDGE_ROCOCO_TO_BULLETIN_MESSAGES_PALLET_INDEX constant because of latest changes * also change indices in runtime * fmt * clippy
