Re-enable running our eslint rules using ts-node (#159495)

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/`

.eslintplugin/code-no-standalone-editor.ts
