Support PNA and multi hops transfer

[yrong]

Details

Index the transfer for PNA asset

Index the transfer from/to 3rd Parachain with multiple-hops, add three new fields:

• forwardedBlockNumber is the block that forwards the transfer on AH
• bridgedBlockNumber is the block that bridges the transfer on BH
• destinationBlockNumber is the block on the destination chain,
  • For the ToPolkadot direction, the 3rd Parachain.
  • For the ToEthereum direction, Ethereum.

type TransferStatusToPolkadot @entity {
  id: ID!
  ...
  status: String! @index
  forwardedBlockNumber: Int
  bridgedBlockNumber: Int
  destinationBlockNumber: Int
}

type TransferStatusToEthereum @entity {
  id: ID!
  ...
  status: String! @index
  forwardedBlockNumber: Int
  bridgedBlockNumber: Int
  destinationBlockNumber: Int
}

export enum TransferStatusEnum {
  // Sent on source chain
  Sent = "Sent",
  // Bridged on BH
  Bridged = "Bridged",
  // Forwarded on AH
  Forwarded = "Forwarded",
  // Processed | ProcessFailed on destination
  Processed = "Processed",
  ProcessFailed = "ProcessFailed",
}

Hydration would be a higher priority than moonbeam initially.

I think we only need this one I think. The others cannot accept XCM so cannot trigger a direct transfer to ethereum.

Do not think we need any runtimes before 3100.

It's auto-generated, and some types are reused in multiple versions.

Yeah, understood. Just did not find a demo transfer message from Hydration which I can use to test. @alistair-singh , have we tested the multi-hops transfer for Hydration?

Btw: The process logic for Moonbeam should most probably apply to Hydration.
