Allow registering constructor for a set of dynamic types
This feature is needed to register complex types (e.g. Q_GADGETS) at
runtime, using a single constructor method and added type parameter.
Without having the type id available to the Constructor it is impossible
to specialize behavior, thus requiring separate constructors for each
type. Generating these separate constructors at compile time is easy,
but not at runtime.
[ChangeLog][QMetaType] QMetaType can now register constructor for a set
of dynamic types.
