[php-src] Issue #8414: `ReflectionClass::newInstance` and `ReflectionClass::newInstanceArgs` are not strict

Issue: https://github.com/php/php-src/issues/8414 Comment Author: iluuu1994 https://3v4l.org/r7atB This has been like this since strict_types are supported. The constructor is called from the internal newInstance method which does not have strict_types enabled. Similarly, something like array_map will invoke the closure without strict_types and thus do type coercion. https://3v4l.org/isV9d ```php declare(strict_types=1); array_map(function (string $i) { var_dump($i); }, [1, 2, 3]); ``` > string(1) "1" > string(1) "2" > string(1) "3" I think it's not completely unreasonable to expect strict_types to be applied to internal functions but it would also be a large BC break.
