Move CDT to C++20, and allow contracts to use C++20
Allow contracts to compile C++20. In addition to the benefits from the latest language features. Currently, ENF maintains an additional fork of one of our upstream dependencies for EOS EVM simply to get around the fact that the upstream assumes C++20 but we cannot build C++20 code in our contracts.
