Resubmission of #157532 with the following changes:
- Use `eslint-plugin-local` instead of `yarn` link to run our plugins
- Move our plugins to a top level `.eslintplugin` dir (as required by `eslint-plugin-local`)
- Update all names to `local/`
* Run our custom eslint rules using ts-node
Use `ts-node` to run our custom eslint rules. This lets us delete the pre-compiled js. It also means you can don't have to compile the rules while editing them
As part of this change, I've also switched us to using an eslint plugin instead of a rulesDir. This is now the preferred way to ship custom rules
* Fix two more disables
* Move ts-node to project root
* Enable transpileOnly
