Modernizing c++ code

[tsjung75]

Do you have any plan to modernize generated c++ code by using c++ 23?

Not just using std::optional or std::span, also complete rewriting for simplicity, readability like protobuf.
Cascading get/set, simplest easist API.

I would like to modernize the code used in flatc to be more modern, as it easier to build that with modern toolchains/compilers. The support for the generated code still has to target older standards (we still support C++11), so I don't envision that being changed any time soon. We could add targeted support for C++20 and C++23 features, like we have for C++17, but it wouldn't be a full rewrite.

It just a lot of work to do.
