Rococo/Wococo bridge hub relay integration (#1565)

* [BridgeHub] Added bridge-hub-rococo/wococo clients with bridge-hub-rococo-runtime * [BridgeHub] Add init-bridge stuff for bridge-hub-rococo/wococo * [BridgeHub] Add init-bridge stuff for bridge-hub-rococo/wococo * [BridgeHub] Fixed Call-encoding for init-bridge rococo runtime wrapper * Final index update to runtime calls * [BridgeHub] Add init-bridge stuff for bridge-hub-rococo/wococo (otherside) * Added runtime best_finalized functions + relay-headers init * Renaming and change BridgeHubRococo/Wococo to Rococo/Wococo config * [BridgeHub] Add relay-parachains (Rococo/Wococo) * Missing stuff for adding xcm messaging to BridgeHub * extracted parachain IDs to the primitives * fix compilation * Fixes * Init setup for Rococo->Wococo messaging support * Removed unused AccountId from `trait MessagesBridge` * Removed unused trait SenderOrigin * Small fixes * Cleaning after master-merge * Fixes * Fixes * Fixes * Fixes * Fixes: - align WeightToFee with BridgeHubRococo runtime - MAX_HEADER_SIZE - updated TODOs * Added relay_messages cfg for BridgeHubWococo -> BridgeHubRococo Co-authored-by: Svyatoslav Nikolsky <svyatonik@gmail.com>
