[DDC-2224] convertToDatabaseValueSQL() is not honored for DQL query parameters

Following discussion on Google Groups:
https://groups.google.com/d/msg/doctrine-dev/-/gG-VGiAGQiMJ

When using a mapping type which declares convertToDatabaseValueSQL(), this method is not invoked when passing a value as parameter to a DQL query.

For example, if I declare a mapping type MyType:

class MyType extends \Doctrine\DBAL\Types\Type
{
    public function canRequireSQLConversion()
    {
        return true;
    }

    public function convertToDatabaseValueSQL($sqlExpr, AbstractPlatform $platform)
    {
        return sprintf('FUNCTION(%s)', $sqlExpr);
    }

    // ...
}

And pass a parameter with this type to a DQL query:

$query = $em->createQuery('SELECT e FROM Entity e WHERE e.field = :field');
$query->setParameter('field', $value, 'MyType');

I would expect the following SQL to be generated:

SELECT ... WHERE ... = FUNCTION(?)

But the current SQL generated is the following:

SELECT ... WHERE ... = ?
