There were a pair of TODOs in constraint gathering in type inference, where objects with .call methods should be considered as if they were subtypes of function types. Fix them. This is a partial fix for https://github.com/dart-lang/sdk/issues/33298 because it does not yet handle the case of generic .call methods.
