Message:

General: Introduce polyfills for str_ends_with() and str_starts_with() added in PHP 8.0.

PHP 8.0 introduced two new functions: str_ends_with() and str_starts_with(). These perform a case-sensitive check indicating if the string to search in (haystack) ends or begins with the given substring (needle).

These polyfills make these functios available for use in Core.

Props costdev, hellofromTonya, pbearne, pbiron.
