QMetaType: Store QMetaObject for pointer to const QObject, too
Before this change, the QMetaType for T const* where T is derived from QObject would not store the static QMetaObject of T. This commit changes this. As a consequence, the metatype system can now convert between const and non-const pointers to QObject. Note that this allows casting const away; but so does C++ with const_cast. In addition, a new flag, QMetaType::IsImmutable is introduced, and used to tag the metatypes of pointer to const types. This allows code to discern between pointers to mutable and const QObjects, which is relevant for the QML engine.
