Add CXX to the project with C++20 (no extensions) and build C++ sources with -Wextra -fno-exceptions -fno-rtti -fno-threadsafe-statics on top of the existing warning flags. Give every toolchain a C++ compiler: the zig Windows toolchain, the static macOS/Windows CI jobs, the static musl image (clang++ plus libstdc++ headers) and the RPM spec.
