Issues with C++17 and Lambda expressions

[lyn19417]

Context

I'm trying to have all my projects use a common version of C++ for consistency. However it seems that Kaguya doesn't well support C++17.

Kaguya Version: master branch
Environment: MSVC (v143)

Example

I have functions which I expose to lua defined through the use of lambda expressions.

state["testLambda"].setFunction([](int a) -> int {
    return a + 10;
});

This code will not compile under Kaguya with C++17 and give the following error (along some more which are only side effects of the first one):

use of undefined type 'kaguya::util::FunctionSignature<kaguya::nativefunction::call::ftype,void>'

More trouble...

After some digging, I got to fix THIS error by modifying utility_cxx11.hpp but now I'm faced with a second issue with detail::invoke_helper which cannot find a matching overload. I tried a bunch of things but none really worked.

I tried with replacing the util::invoke to the one from the standard library std::invoke but it gives exactly the same issues. Probably something related with how Kaguya handles things.

For now I will stick with C++14 until this (hopefully) gets fixed.
