Enhance the batchRegisterIpAssetsWithOptimizedWorkflows method support multiple erc20 tokens

Is your feature request related to a problem? Please describe.
The batchRegisterIpAssetsWithOptimizedWorkflows method currently needs to handle a large number of arguments. In some scenarios, token payments must occur simultaneously.

For example:

1. We create two spgNftContract instances using different ERC20 tokens (spgNftContractForERC201 and spgNftContractForERC202):

const publicMintingCollectionResult = await client.nftClient.createNFTCollection({
  name: "Public Minting Collection",
  symbol: "PMC",
  isPublicMinting: true,
  mintOpen: true,
  mintFeeRecipient: TEST_WALLET_ADDRESS,
  mintFee: 10n,
  mintFeeToken: erc20Token, // different ERC20 token
  contractURI: "",
});

2. Then we call batchRegisterIpAssetsWithOptimizedWorkflows as follows:

const result = await client.ipAsset.batchRegisterIpAssetsWithOptimizedWorkflows({
  requests: [
    {
      spgNftContract: spgNftContractForERC201,
      derivData,
    },
    {
      spgNftContract: spgNftContractForERC202,
      derivData,
    },
  ],
});

Because both requests share the same structure, they are grouped and executed via multicall in the DerivativeWorkflows contract.
However, the current method does not support paying multiple ERC20 tokens within a single multicall, nor does it support auto-approval for multiple tokens. This prevents the workflow from being executed successfully when different token payments are involved.

Describe the solution you'd like
Enhance the method so that it can:

• Support multiple ERC20 token payments within the same batch request.
