What does this implement/fix? Explain your changes.

Previously when a C# method with a parameter of type object was called from Python with some argument of a native Python type (e.g. instance of dict rather than instance of System.Random), that would be considered a parameter type mismatch, so overload resolution would fail, and the C# method would not be called.

After this change, when Python tries to pass a argument of some Python type to a C# parameter of type object, that overload would be considered good for resolution, and the argument will be wrapped into PyObject and passed to the object parameter.

For example:

void CallMe(object anything) => Console.WriteLine(anything);

CallMe(dict())

Before change: overload not found
After change: anything in CallMe is an instance of PyObject, wrapping a dict instance, so CallMe outputs {}

Does this close any currently open issues?
