Feature request: \Codeception\Module\Filesystem::writeToFile create a directory recursively.

Scenario:

I want to create a file inside a folder:
`$I->writeToFile('/var/www/foo/foo.php', '');`

This will fail because the folder `foo` does not exist.

Now I have to create the folder recursively and keep track of it for deletion.

```
public function writeToFile($filename, $contents)
{
file_put_contents($filename, $contents);
}
```

This issue is a feature request to make that method more robust, using perhaps Symfony Filesystem to recursively create the directory. Eg: https://symfony.com/doc/current/components/filesystem.html#mkdir

从 Codeception\Module\Filesystem::writeToFile 开始，检查模块现有的测试（如果有）。验证向缺失的嵌套目录中的文件写入能够成功，并且现有行为保持不变；完成时应覆盖 issue 中描述的递归目录场景。
