QmlCompiler: Do not use QQmlEngine from current QML context
We cannot be sure the current context is still alive when a function is
called. We may be left with a skeleton context that doesn't have an
engine anymore.
However, we can always query the QJSEngine given in the AOT context.
That one cannot disappear and is generally the right one for capturing
properties.
Pick-to: 6.7 6.5 6.2
Fixes: QTBUG-123395
