Add support for exposing public QProperty members in the meta-object system

At the moment this makes the type as well as the setter/getter available
through the meta-call as well as the ability to register observers and
bindings. Only QProperty members that are annotated with
Q_PROPERTY(type name) are made public through the meta-object.
