[php-src] Issue #7910: rename fails on Windows PHP 8.1 if the target file is being executed

Issue: https://github.com/php/php-src/issues/7910 Author: johnstevenson ### Description The following code: ```php <?php // file: bug.php $content = file_get_contents(__FILE__); file_put_contents('newfile.php', $content."\n//"); var_dump(rename('newfile.php', __FILE__)); ``` Resulted in this output: ``` PHP Warning: rename(newfile.php,C:\Users\John\projects\test\bug.php): Access is denied (code: 5) in C:\Users\John\projects\test\bug.php on line 6 Warning: rename(newfile.php,C:\Users\John\projects\test\bug.php): Access is denied (code: 5) in C:\Users\John\projects\test\bug.php on line 6 bool(false) ``` But I expected this output instead: ``` bool(true) ``` This code mimics how Composer self updates (https://getcomposer.org/doc/03-cli.md#self-update-selfupdate-) and has obviously worked for many years, but is broken on Windows PHP 8.1: https://github.com/composer/composer/issues/10444 Note that on Composer 2 we now use copy on Windows (to get around potential permission issues in UAC protected locations) and this still works on PHP 8.1, but Composer 1 uses rename (as do all non-Windows platforms on all Composer versions). Fortunately, this appears to be a Windows only thing, as per this demo: https://github.com/johnstevenson/php-rename-bug/actions/runs/1669358275 ### PHP Version PHP 8.1.0 ### Operating System Windows 10
