fails with mysqli adapter on PHP 8.0

[croensch]

When using the mysqli adapter (Zend_Db_Statement_Mysqli):

mysqli_stmt::bind_param() does not accept unknown named parameters

I believe this is because even though Zend_Validate_Db_Abstract->getSelect() checks if the adapter supports named parameters, and if not builds the query with a positional parameter, it always binds a named parameter in ->_query().

The tests don't cover this yet.

@croensch do you think you could put together a simple failing test case, even if it's just a snippet? We don't use Zend_Db ourselves so haven't run into this.

I simulated what Mysqli would expect (positional parameters). If that is reasonable i can code the fix too.
