Sam McCall 4cae6228d1 [ADT] function_ref's constructor is unavailable if the argument is not callable. ...

This allows overload sets containing function_ref arguments to work correctly
Otherwise they're ambiguous as anything "could be" converted to a function_ref.

This matches proposed std::function_ref, absl::function_ref, etc.
