Several PHP functions that have not been doing anything since PHP 8.0/8.1, specifically: * `finfo_close()` since the `ext/fileinfo` migration in PHP 8.1 * `xml_parser_free()` since the `ext/xml` migration in PHP 8.0 * `curl_close()` since the `ext/curl` migration in PHP 8.0 * `curl_share_close()` since the `ext/curl` migration in PHP 8.0 * `imagedestroy()` since the `ext/gd` migration in PHP 8.0 will be deprecated in PHP 8.5 and will thus be throwing warnings. This commit adds conditional checks to only call these functions on the relevant PHP versions.
