Issue:
Write utility to print contract sizes, and add test in CI that fails if any contract is oversized

Pull request:
Add hardhat plugin for contract sizes
Fix #550

The plugin [hardhat-contract-sizes](https://github.com/ItsNickBarry/hardhat-contract-sizer) was added to the packages:
* core-contracts
* core-modules
* synthetix-main

Which adds a new `npx hardhat size-contracts` hardhat task.

This PR also adds GA tests for checking if any contract is oversize in CI.

FYI, all contracts appear to be very small rn.
