transfer DOT/KSM to and from Asset Hub during AHM

[brenzi]

AHM migration will change the reserve location of DOT/KSM. This is why transferAssets and limitedReserveTransferAsset are disabled during AHM

The following calls work nevertheless (as long as the reserve is correct: check depending on whether you call thsi pre- or post migration)

pre-AHM calls using polkadotXcm.transferAssetsUsingTypeAndThen:

• DOT from PAH to IP
• DOT from IP to PAH
• KSM from KAH to IK
• KSM from IK to KAH

tested with chopsticks:

npx @acala-network/chopsticks@latest xcm --p=./configs/polkadot-asset-hub.yml --p=./configs/integritee-polkadot.yml
using runtime overrides:

• asset_hub_polkadot_runtime_1.7.1_debug.compact.compressed.wasm
• integritee_polkadot_runtime-561-dev.compact.compressed.wasm

npx @acala-network/chopsticks@latest xcm --p=./configs/kusama-asset-hub.yml --p=./configs/integritee-kusama.yml
using runtime overrides:

• asset_hub_kusama_runtime_1.7.1_debug.compact.compressed.wasm
• integritee_kusama_runtime-561-dev.compact.compressed.wasm

onchain evidence that it actually works (pre-AHM):

• TEER from IP-> PAH: IP PAH
• TEER from PAH->IP: PAH IP
• DOT from PAH -> IP: PAH IP
• DOT from IP->PAH: IP PAH

• DOT from PAH to KAH
