[Feature] Consider moving from ethereum-waffle to hardhat-chai-matchers

[boyuanx]

Feature Description

@nomicfoundation/hardhat-chai-matchers contains a few features and bug fixes that ethereum-waffle does not possess and greatly benefited my work, for example:

• ethereum-waffle cannot match custom errors introduced in Solidity 0.8.4
• ethereum-waffle sometimes fails to properly compare BigNumber and BigNumberish while @nomicfoundation/hardhat-chai-matchers seems to have better support for this
• The matcher syntax generally remains the same, so no need to extensively rewrite legacy code

Additional Information

For instance, when performing .deep.equal on BigNumber[] and PromiseOrValue<BigNumberish>[], ethereum-waffle fails this comparison despite the underlying numbers being the same.

Also just a side note, I wonder if there is a better way to compare structs (without mappings in them) than comparing their properties individually.
