add custom data for zksync

[zjesko]

Add the ability to pass customData along with overrides to enable paymaster and other interactions.

More details:
As defined in ethers, we can pass an extra override customData which is used for passing along for network-specific values for networks like zksync and sophon.
https://github.com/ethers-io/ethers.js/blob/main/src.ts/providers/provider.ts#L198

This PR adds the ability to pass customData as part of overrides.
Taken inspiration from hardhat-zksync-deploy
https://github.com/matter-labs/hardhat-zksync/blob/main/packages/hardhat-zksync-deploy/src/deployer-helper.ts#L101

A very good use case is zksync/sophon paymaster deployments.

Example usage for sophon network:

export default async function (hre: HardhatRuntimeEnvironment) {
    console.info(chalk.yellow(`Running deploy script for the Greeting contract`));

    const constructorArguments = ["Hello World"];

    const {deployments, getNamedAccounts} = hre;
    const {deploy} = deployments;

    const {deployer} = await getNamedAccounts();

    const params = zk.utils.getPaymasterParams(
      "0x98546B226dbbA8230cf620635a1e4ab01F6A99B2", // Sophon default paymaster address
      {
        type: "General",
        innerInput: new Uint8Array(),
      }
    );

    const contract = await deploy('Greeter', {
      from: deployer,
      args: ["Hello World"],
      log: true,
      customData: {
        paymasterParams: params,
        gasPerPubdata: zk.utils.DEFAULT_GAS_PER_PUBDATA_LIMIT,
      }
    });

    console.info(chalk.green(`Greeter was deployed to ${contract.address}`));
}
