Use QQmlType for looking up enums, even on singletons
QQmlType has more information than the bare QMetaType. The optimizer
already uses it for looking up enums, so some code would behave
differently, depending on whether the optimizer was enabled or not.
In some cases we cannot use QQmlType for lookup of enums because
QQmlType might have been created with only a callback. The object
only shows up later in that case. Then the only thing we can do is
query the metatype.
We can test this by adding an eval() because eval() disables
optimization for the surrounding code.
