Subject: [PATCH 1/2] Feat flush view data

The view data keeps appending causing memory to increase.

For example.

There is a timed task to send emails, I send 100 emails with different data, the view data length will be 100, the data volume is large but the memory is relatively small, it can easily lead to killed.

```php
        for ($index = 0; $index < 100; $index++) {
            /* @var Factory $viewFactor */
            $viewFactor = Mail::getViewFactory();

            $view = $viewFactor->make('email.view', [
                // ......
            ]);

            // get html
            $data = $view->render();

            /* @var CompilerEngine $viewEngine */
            $viewEngine = $view->getEngine();
            $viewEngine->flushViewData();

            // send mail via raw data
            // ......
        }
```
