Documentation: Add \nullptr macro and use where applicable
Qt for Python users reading the documentation assume that int(0) can
be passed for pointer parameters. Use the newly introduced \nullptr to
disambiguate this.
In a follow-up step, the \nullptr macro can be defined as None
when generating the Qt for Python documentation.
