[!!!][TASK] Migrate Extbase Query Parser to Doctrine DBAL

The Extbase Typo3DbQueryParser which builds the SQL
statement for most of Extbase's database calls is completely
rewritten to use Doctrine DBAL QueryBuilder.

The QueryParser now returns a properly filled QueryBuilder
object instead of an array with SQL parts.

The Typo3DbBackend of Extbase is using the QueryBuilder
under the hood then.
