implement QScriptContextInfo::parameterNames() for Qt methods

It doesn't work for overloaded methods yet (unless you just
happened to call the overload that's defined last in the source
file).
In the old back-end we stored the actual overload that was being
called in the QScriptContextPrivate. Since QScriptContext is a
JSC::ExecState now, we either have to add the information to
JSC::ExecState, or add some mapping scheme so we can go
determine the meta-index for a particular (ExecState, QtFunction)
pair.

Also in this commit: Marked expected failures, so the autotests
will run to completion.
