Add helper that allows us to determine the argument list and return type of a functor. This triggers a compile time error if the functor has operator()() overloads (we only support zero-argument call operators, but there might be const/noexcept variations). Use that helper to declare a ZeroArgFunctor type which also declares a ReturnType and Arguments alias. Add a Callable alias that now combines FunctionPointer and ZeroArgFunctor into a single type that we can then use to merge the specializations of QMetaObject::invokeMethod. [ChangeLog][Potentially source-incompatible changes] Using a functor with several operator() overloads in QMetaObject::invokeMethod now causes a compile time error. Qt would previously ignore const and noexcept overloads and always call the mutable version on a copy of the functor.
