Remove (rococo/westend)-runtime deps from testnet AssetHubs (#1979)

## Problem

This PR addresses the issue with testnet AssetHub builds, which was
discovered during the execution of `bot bench`.

https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4038738
```

## Solution

- Removed dependencies on `rococo-runtime` and `westend-runtime`
introduced by [this
PR](https://github.com/paritytech/polkadot-sdk/pull/1234/files#diff-a86375df98e04ca3cce1ea35c40257a222e2d5087f5f528ff33307678b78dc2dR534-R550).
- Replaced `<rococo_runtime::Treasury as PalletInfoAccess>::index()`
with `rococo_runtime_constants::TREASURY_PALLET_ID`.
- Added `check_treasury_pallet_id` to the relay runtimes to ensure that
the constant is aligned with the pallet id.
- Added "Rococo Treasury" to the waived locations (that will not be
charged fees in the executor) for `BridgeHubRococo` (to be aligned with
AssetHubs).
