Implemented writeTextBlock method in Zend\Console\Adapter\AbstractAdapter

I noticed that the `Zend\Console\Adapter\AbstractAdapter::writeTextBlock()` method was not implemented, so I implemented it, added tests, and ran `php-cs-fixer`.

Also, in order to be able to verify how this method writes data, I added an array to the test asset class `ConsoleAdapter`. Without this tracking array, the output buffering doesn't correctly show which data I expect since there isn't a way to track text in between calls to `AbstractAdapter::setPos()`.
