findChild is missing options argument

The templated QObject::findChild takes two arguments, a name argument and an options argument.  The PySide2 version only supports the name argument.

% python3
>>> from PySide2.QtCore import QObject
>>> help(QObject.findChild)

Help on method_descriptor:

findChild(self, arg__1:type, arg__2:str='') -> object

 The first argument is the template argument.  The second argument should be "name", not "arg__2", and the third argument is missing.
