[Process] Add support SAPI cli-server

As of PHP 5.4.0, the CLI SAPI provides a built-in web server.
```php
PHP_SAPI == 'cli-server'
```
PHP can be used portable without installation on PC. For example, the [assembly](http://windows.php.net/download/) does not require installation in the system on Windows. In this case `PHP_BINARY` contains the path to the PHP executor, and all the other search methods will not return result.
