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 Props ayeshrajans, costdev, desrosj, hellofromTonya, knutsp, pbearne. Fixes #49652. git-svn-id: https://develop.svn.wordpress.org/trunk@52039 602fd350-edb4-49c9-b593-d223f7449a82
