[php-src] Issue #8090: ReflectionParameter::isDefaultValueAvailable() returns false negative if next parameter is not optional.

Issue: https://github.com/php/php-src/issues/8090 Author: pronode ### Description The following code: ```php class Test { public function foo(int $id = 1, string $str = 'default') {} public function goo(int $id = 1, string $str) {} public function moo(int $id = 1) {} } var_dump((new \ReflectionMethod(new Test(), 'foo'))->getParameters()[0]->isDefaultValueAvailable()); var_dump((new \ReflectionMethod(new Test(), 'goo'))->getParameters()[0]->isDefaultValueAvailable()); var_dump((new \ReflectionMethod(new Test(), 'moo'))->getParameters()[0]->isDefaultValueAvailable()); ``` Resulted in this output: ``` bool(true) bool(false) bool(true) ``` But I expected this output instead: ``` bool(true) bool(true) bool(true) ``` ### PHP Version PHP 8.1.1 ### Operating System Windows 10
