Is your feature request related to a problem? Please describe.

Similar to how cuda::std::invoke_result has a static_assert warning about accessing extended lambda return type from host where its not available, it would make sense to add such assert to cuda::std::is_invocable. Right now it just always returns true, no matter what argument types are passed into it

Describe the solution you'd like

It would be nice if is_invocable would fail to compile when used in host code on an extended lambda

Describe alternatives you've considered
