feat(protocol): Additional integration tests, solidity bump, reduce TokenVault contract size

[cyberhorsey]

This adds some additional integration tests, as well as updates Solidity to 0.8.18 so we can take advantage of the named mapping parameters function, which definitely helps readability on some of our more complex mappings, and removes the need for comments. It also fixes the linter/type errors on the new customError handling functions, as well as hardhat-contract-sizer to get to the bottom of the large contract which is failing our CICD randomly, which turned out to be the TokenVault, which is almost at 24.5kb max contract size. I got it down to 22.7kb with custom errors refactoring and slight modifications elsewhere, and now it seems to not fail our CICD.

However, solhint is not ready for named parameter mappings just yet:
protofire/solhint#397

I can go ahead and undo those changes if we want to wait for solhint to be ready for us before we do this change.

@dantaik as well, in solidity 0.9.0, block.difficulty will be removed from Solidity, which we use for setting the mixHash when proposing a block.

No need to care about the solint errors.

I'll take a look.

I believe we should use block.prevrandao instead, which was introduced in solidity 0.8.18:

And seems there are some errors in github action (test:tokenomics), hmm not sure if its because of the changes in this PR ?

[dantaik]

@cyberhorsey I accidentally merged my PR onto yours before fixing test bugs. Please undo the last PR of mine.

[cyberhorsey]

@dantaik @davidtaikocha solidity-coverage library is not ready for new solidity features, and the repo is potentially semi-abandoned (hanging open issues and PRs for quite some time).

I have submitted a PR to fix the repo so it works with 0.8.18:
sc-forks/solidity-coverage#783
But I am unsure if it will be merged in. In the meantime, I have changed our dependency to point to my fork. Let me know if that isn't OK with you. I could also fork it under the taikoxyz org, or we could disable coverage.

I could also fork it under the taikoxyz org, or we could disable coverage.

I think we can fork the repo under taiko's account.

OK, done
