#### Summary

<!-- Provide a summary describing the problem you are experiencing. -->

`Doctrine\ORM\QueryBuilder::setParameter()` needs an optional parameter for complex data types sometimes and in 3.x version, it expects `string|int|null` and can be linked via `Doctrine\DBAL\Connection` e.g. `Doctrine\DBAL\Connection::PARAM_STR_ARRAY`. These values used to be as int datatype and have been deprecated. Now these constants are linked to `Doctrine\DBAL\ArrayParameterType` class. In 4.0.0 class ArrayParameterType has been converted to Enums but setParameter() is still accepting old `string|int|null` resulting following error

Pull request:
Allow (Array)ParameterType in QueryBuilder
Replaces #11279, fixes #11278.

This PR continues the work done by @hanishsingla and adds a few tests.

Changing the signature of `QueryBuilder::setParameter()` is technically a BC break, but we cannot fix the bug without breaking BC, I'm afraid. Let's hope nobody overrides the `setParameter()` method of 3.0 yet. 🤞🏻
