Added `QueryInterface::emulateExecution()`, which allows preventing of
the actual query execution.
This allows to cancel `DataProvider` preventing search query execution
in case search model is invalid:
``` php
public function search($params)
{
$query = Item::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
$query->where('0=1');
$query->emulateExecution(); // No SQL execution will be done
return $dataProvider;
}
```
This also fix unecessary query in case of `via()` usage. See #12390.
