Add QUntypedBindable::metaType function

This enables checking the metaType of a QUntypedBindable in the public
interface.
In addition, work around an oversight that can only be fully addressed
in Qt 7: The metatype function pointer does not take a
QUntypedPropertyData * parameter. However, we need this functionality
for an efficient QBindable proxy implementation in declarative (which is
needed to implement interceptors there). To work-aronud this in Qt 6,
reuse the value getter and turn it into a metatype getter if the value
pointer is flagged.
