Add webpack bundled size checks for client imports

Add @size-limit/webpack to measure realistic bundle sizes when users
import from the packages:
- react-on-rails/client
- react-on-rails-pro/client
- react-on-rails-pro/registerServerComponent/client
- react-on-rails-pro/wrapServerComponentRenderer/client

Use "webpack": false for glob-based entries to prevent bundling server
files that have Node.js dependencies.
