Re-registration of enum types doesn't work

If I do the following

cpp:
qmlRegisterType<MyType1>("MyModule", 1, 0, "MyType");
qmlRegisterType<MyType2>("MyModule", 1, 0, "MyType");
runSomeQmlApplication();

qml:
MyType{ ... }

then QML will instantiate MyType2. This makes sense, it was the last type to be registered.

However, if I both MyType1 and MyType2 has an enum value ENUM_VAL, then doing MyType.ENUM_VAL will use MyType1::ENUM_VAL even though MyType2 is instantiated

Related to QTBUG-56521 and blocking workaround for QTBUG-56172.
