[testnet] Add AssetHubRococo <-> AssetHubWestend asset bridging support (#1967)

## Summary Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was added [here](https://github.com/paritytech/polkadot-sdk/pull/1215), so now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And perhaps retire AssetHubWococo and the Wococo chains). ## Solution **bridge-hub-westend-runtime** - added new runtime as a copy of `bridge-hub-rococo-runtime` - added support for bridging to `BridgeHubRococo` - added tests and benchmarks **bridge-hub-rococo-runtime** - added support for bridging to `BridgeHubWestend` - added tests and benchmarks - internal refactoring by splitting bridge configuration per network, e.g., `bridge_to_whatevernetwork_config.rs`. **asset-hub-rococo-runtime** - added support for asset bridging to `AssetHubWestend` (allows to receive only WNDs) - added new xcm router for `Westend` - added tests and benchmarks **asset-hub-westend-runtime** - added support for asset bridging to `AssetHubRococo` (allows to receive only ROCs) - added new xcm router for `Rococo` - added tests and benchmarks ## Deployment All changes will be deployed as a part of https://github.com/paritytech/polkadot-sdk/issues/1988. ## TODO - [x] benchmarks for all pallet instances - [x] integration tests - [x] local run scripts Relates to: https://github.com/paritytech/parity-bridges-common/issues/2602 Relates to: https://github.com/paritytech/polkadot-sdk/issues/1988 --------- Co-authored-by: command-bot <> Co-authored-by: Adrian Catangiu <adrian@parity.io> Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com>
