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

Assets Parachain

Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".

Asset Hub allows users to:

  • Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
  • Set admin roles to manage assets and asset classes.
  • Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existance of accounts sans DOT/KSM.
  • Pay transaction fees using sufficient assets.
  • Transfer (and approve transfer) assets.
  • Interact with the chain via its transactional API or XCM.

Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.

See the article on Asset Hub as common good parachain for a higher level description.

Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
