Use canonical balances pallet and add support for assets in wormhole

[dastansam]

This PR does mainly two things:

• Get rid of balances pallet fork and consolidate proofs in the wormhole pallet instead. Proofs, transfer count, and nullifiers all are now stored in the wormhole pallet.
• Add new wormhole proof recorder transaction extension that intercepts successful (post-dispatch) asset and native token transfers and records their transfer proof. Similar to reversible transactions extension except for post dispatch nature. Additionally, there are two new extrinsics in the wormhole pallet for native and asset transfers (they won't be intercepted by the tx extension)

did we lose this test entirely?

[dastansam]

no, it's back in later commits

[illuzen]

overall LGTM, can we go back to having descriptions on PRs? Maybe just make them like one paragraph

[ethan-crypto]

LGTM. Happy to help here https://github.com/Quantus-Network/qp-zk-circuits/pull/55/changes to get the entire proving and verification flow working end 2 end ASAP.

Please update the wormhole branch first, and then add here only the changes you actually need.
