migrate ignition-core to Hardhat 3

[kanej]

Migrate @nomicfoundation/ignition-core to Hardhat 3.

We move all of Ignition's packages under ./packages to a ./tmp-ignition folder, taking Ignition out of the build. We then bring ignition-core under v-next, make it support ESM and wire it into the Hardhat 3 setup more generally.

Resolves #6207.

Approach

1. Move the ignition-core files under ./v-next
2. Update the code to match updated prettier and eslint rules
3. Re-enable API extractor checks as part of linting
4. Switch to ESM for the package
   1. Change any code patterns that are implied by this (e.g. switching to dynamic imports)
   2. Update or swap dependencies to work with ESM
5. Update unit tests (pnpm run test) until all are passing (retaining mocha for the moment)
6. Update Integration tests (pnpm run test:integrations) until all are passing (retaining mocha for the moment)

TODO

• Move ignition-core to v-next folder with working build (but not tests)
• Update prettier and apply formatting
• Update to typescript 5.5
• Update the API extractor
• Use defineProperty for inspect pattern while support isolated declarations
• Update eslint packages and rules, apply fixes
  • Some rules are disabled
• Fix up mocha unit tests
• Disable integration tests (we will revisit in a follow up PR)
• Switch to ESM
  • Update __dirname usage
  • Replace fs in utils with hardhat-utils
  • Replace dynamic requires with dynamic imports
  • Replace cbor with cbor2
• Rename package to v-next convention

Follow up tasks

• Port Ignition Errors to Hardhat 3
• Re-enable integration tests (deal with Hardhat project fixtures)
• Update codebase so no eslint rules are disabled
• Port lodash calls to hardhat-utils
• Port address related calls to hardhat-utils
• Port ethers calls to hardhat-utils
• Update imports of ./src/index.js to be more specific (we should avoid relying on
  index.js files)
• Re-enable npm scripts comparison check in CI (we need to wait until Node Test Runner move is complete).
• Look again at chai and chai types versions, I tried bumping up the version to match Ignition and ended up moving it down to match hardhat-chai-matchers
