[MS ABI] Pick an inheritance model if we resolve an overload set
We didn't assign an inheritance model for 'Foo' if the event an
exrepssion like '&Foo::Bar' occured if 'Bar' could resolve to multiple
functions.
Once the overload set is resolved to a particular member, we enforce a
specific inheritance model.
This fixes PR28360.
