Add QtCore.Slot.__signature__ and much more manually

The signature of QtCore.Slot and other classes could not automatically
be generated because the function is not generated by cppgenerator.cpp .
We add it manually in the C++ code into the generation process.

The case of QtCore.Slot had diverse follow-up issues to be solved:

- Classes which did not inherit from Shiboken were not generated.
  This is a long-standing omission and creates very many new
  simple types.

- The arity of Slot has default arguments after the varargs parameter
  "*types". This needed an extended Python parser analysis that fixes
  the arguments given to the inspect module, accordingly.

- The signature generation was completely new implemented and
  relies no longer on the restricted syntax of a Python (2) function
  but generates signatures directly as Parameter instances.

Implemented classes with hand-made signatures:

    QtCore.ClassInfo
    QtCore.MetaFunction,
    QtCore.MetaSignal
    QtCore.Property
    QtCore.Signal
    QtCore.SignalInstance
    QtCore.Slot
    QtQml.ListProperty
    QtQml.VolatileBool

As a side effect, many more subtypes were published.
Enums are done, which concludes this work.
