Remove detection of unsupported Windows versions (phpGH-15399)

Windows 2008 and Vista are no longer supported as of PHP 7.2.0, and
Windows 2008 R2 and Windows 7 are no longer supported as of PHP 8.3.0.
Therefore we remove the respective detection code, and assert that
these versions can no longer be used.
