Expose Shiboken generated Python module object

This change exposes the module object (a PyObject*) to the global
namespace as Sbk[TYPESYSTEM NAME]ModuleObject. This is useful when
generating bindings for cases where Python will run embedded into
a host application.
This variable is also included in the headers, where it is
declared as `extern PyObject* Sbk[TYPESYSTEM NAME]ModuleObject;` for
the convenience of developers reading the generated sources.
