Setup testnet system parachain runtimes benchmarking for delivering to sibling parachains instead of Parent

[bkontur]

Description

Currently, all system parachains benchmarking setups for pallet_xcm::benchmarking::Config or pallet_xcm_benchmarks::Config are written to deliver to the Parent (i.e., the relay chain), such as for all asset transfers.

As we are transitioning functionality, like balances, from the relay chain to the asset hubs, we need to update these benchmarks to reflect this migration.

Relevant Changes

Delivery Helpers:
Replace DeliveryHelpers that use cumulus_primitives_utility::ToParentDeliveryHelper (example) with polkadot_runtime_common::xcm_sender::ToParachainDeliveryHelper (example).

Destination Updates:
Review and update all destinations used in the benchmarks, including:

• fn valid_destination()
• fn subscribe_origin()
• fn set_up_complex_asset_transfer()
• TrustedTeleporter
• ...

This ensures the benchmarks are aligned with the changes in architecture and accurately reflect the new delivery paths.

TODO/Progress

• revisit/fix all system parachain benchmark setup for pallet_xcm::benchmarking::Config
• revisit/fix all system parachain benchmark setup for pallet_xcm_benchmarks::Config
• check all other non-xcm benchmarks
• investigate coretime (uses calls to Parent) ?

Hey @bkontur I don't mind picking this up if it's still free

[bkontur]

@EleisonC Do you have an estimate of when you can complete it?

Hey @bkontur I am estimating one day to get a PR up with the first couple of refactors. To complete might depend on feedback involved.

@EleisonC ok, I suggest starting with just one runtime, AssetHubWestend. Once it works as expected, we can simply apply the changes to the others.
