feature(contracts-bedrock): add verify.ts for verifying any contract

[welkin22]

Description

Add a new hardhat task so that we can easily verify the contract

Rationale

The old contract verification method in the current version is invalid, and we cannot verify the contract easily.

Example

npx hardhat opbnb-verify --contract-address 0xc0d3c0d3c0d3c0d3c0d3c0d3c0d3c0d3c0d30007 L2CrossDomainMessenger 0xd506952e78eecd5d4424b1990a0c99b1568e7c2c

You can use npx hardhat help opbnb-verify to view detailed help documentation

Changes

• add verify.ts
• import verify.ts into index.ts

Run command as below:

$ npx hardhat opbnb-verify --contract-address 0xD1917629B3E6A72E6772Aab5dBe58Eb7FA3C2F33 OptimismMintableERC20 0x4200000000000000000000000000000000000010 0xe0BB0D3DE8c10976511e5030cA403dBf4c25165B BTCB BTCB
