Branislav Kontur 1b1fab0da3 [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

Bridges Tests for Local Rococo <> Wococo Bridge

This folder contains zombienet based integration tests for both onchain and offchain bridges code. Due to some technical diffuculties, we are using native zombienet provider, which means that you need to build some binaries locally.

To start those tests, you need to:

  • download latest zombienet release;

  • build Polkadot binary by running cargo build -p polkadot --release command in the polkadot-sdk repository clone;

  • build Polkadot Parachain binary by running cargo build -p polkadot-parachain-bin --release command in the polkadot-sdk repository clone;

  • ensure that you have node installed. Additionally, we'll need globally installed polkadot/api-cli package (use npm install -g @polkadot/api-cli@beta to install it);

  • build Substrate relay by running cargo build -p substrate-relay --release command in the parity-bridges-common repository clone.

  • copy fresh substrate-relay binary, built in previous point, to the ~/local_bridge_testing/bin/substrate-relay;

  • change the POLKADOT_SDK_FOLDER and ZOMBIENET_BINARY_PATH (and ensure that the nearby variables have correct values) in the ./run-tests.sh.

After that, you could run tests with the ./run-tests.sh command. Hopefully, it'll show the "All tests have completed successfully" message in the end. Otherwise, it'll print paths to zombienet process logs, which, in turn, may be used to track locations of all spinned relay and parachain nodes.
