QV4::ExecutionEngine: provide QNAM accessor

In XMLHttpRequest, we need to get the QNetworkAccessManager from the
engine. However, if the request originates from a WorkerScript, there
exists no qmlEngine. We therefore add a new indirection to access the
QNAM, and set it up accordinly in registerWorkerScript.

Fixes: QTBUG-81055
