Unnecessary Files Loaded in Production Environment - Codeigniter 4.1.1

Kint and Laminas are needed dependencies. Removing those will make CI4 break. In `system/CodeIgniter.php` there is a whole method dedicated to initialize Kint, so don't meddle with that. As for symfony polyfills and phpseclib, they may be needed dependencies of those two. So removing those will break those two dependencies and in turn break CI4 ultimately.
