Replace implicit dependence on ext/iconv in JS escaper
Twig's JS escaper fails on non-word characters if `ext/iconv` isn't available. That's because it uses iconv to replace characters with their hex codepoints and split characters outside the Basic Multilingual Plane into surrogate pairs. `symfony/polyfill-iconv` does not support the UTF-16BE conversion and cannot be used as a replacement.
This PR splits the surrogates using native PHP, after obtaining the codepoint via `mb_ord()` which is provided either natively or via `symfony/polyfill-mbstring`, which is already part of Twig's requirements.

Twig, the flexible, fast, and secure template language for PHP
==============================================================
Twig is a template language for PHP, released under the new BSD license (code
and documentation).
Twig uses a syntax similar to the Django and Jinja template languages which
inspired the Twig runtime environment.
