chore: migrate from tslint to @typescript-eslint (#1706)

- update .eslintrc to work for .js and .ts
- update devDependencies
- lint properly both root /src and nested /packages
- update webhint recommended setting for tsconfig.json to shrink output
- Manage all eslint rules from the repo root
- escape single quotes in scripts to please windows build
