General: Introduce polyfills for new array related functions in PHP 8.4.

PHP 8.4 introduced four new functions to provide a common way to more easily perform common operations on arrays.

- `array_find()`: https://www.php.net/manual/en/function.array-find.php
- `array_find_key()`: https://www.php.net/manual/en/function.array-find-key.php
- `array_all()`: https://www.php.net/manual/en/function.array-all.php
- `array_any()`: https://www.php.net/manual/en/function.array-any.php

These functions are now polyfilled making them available on all supported versions of PHP (currently 7.2+).
