General: Introduce polyfill for str_contains() added in PHP 8.0.

Browse Source 
PHP 8.0 introduced a new function: `str_contains()`. It performs a case-sensitive check indicating if given substring (needle) is contained in the string to search in (haystack).

This polyfill makes this function available for use in Core.

Ref:
* PHP RFC https://wiki.php.net/rfc/str_contains
* PHP manual https://www.php.net/manual/en/function.str-contains.php
