Add zkSync diamond support

[gergelyhegykozi]

Fixes #453 and #462

Problem:

• ZkSync requires a different deployment process so we cant reuse the same artifacts.
• {init} argument can't be used for Diamond _initializations.
• Any contract deployment fails on zkSync if it was already deployed (invalid rlp data).

Solution:

• Add optional defaultLoupeFacet parameter, so Diamond facets can be fully defined from outside.
• Use array instead of object for _initializations.
• Compare transaction.data the regular way.

Deployment:

1. step

npm i --save-dev @matterlabs/hardhat-zksync-deploy

2. step

Add these to hardhat config:

import '@matterlabs/hardhat-zksync-deploy';
import '@matterlabs/hardhat-zksync-solc';

Add ethereum and zksync to the networks in hardhat-config.

Example for zksync:

zkSyncMainnet: {
    accounts: ...,
    chainId: 324,
    url: ...,
    ethNetwork: ...,
    zksync: true,
},

3. step

Clone https://github.com/safe-global/safe-singleton-factory and fill out env. Run yarn compile:zk then yarn submit

4. step

Use the generated artifacts and define the deterministicDeployment based on this description: https://github.com/wighawag/hardhat-deploy?tab=readme-ov-file#4-deterministicdeployment-ability-to-specify-a-deployment-factory

5. step

Set contracts path in hardhat config to diamond contracts or create a copy of them.

6. step

In deploy script:

if (['zkSyncTestnet', 'zkSyncMainnet'].includes(hre.network.name)) {
    await hre.deployments.diamond.deploy('YourDiamondName', {
        from: deployer,
        owner: deployer,
        defaultCutFacet: false,
        defaultOwnershipFacet: false,
        defaultLoupeFacet: false,
        diamondContract: 'Diamond',
        facets: [
            facets,
            ['DiamondCutFacet', 'OwnershipFacet', 'DiamondLoupeFacet'],
        ].flat(),
        execute: {
            contract: 'DiamondERC165Init',
            methodName: 'setERC165',
            args: [['0x48e2b093', '0x1f931c1c', '0x7f5828d0'], []],
        },
        diamondContractArgs: ['{owner}', '{facetCuts}', '{init}'],
    });
} else {
    await hre.deployments.diamond.deploy('YourDiamondName', {
      from: deployer,
      owner: deployer,
      facets,
    });  
}

Add optional defaultLoupeFacet parameter, so Diamond facets can be fully defined from outside.

Being able to provide my own loupe implementation would be very nice.
