[native] Use libc++ (#9558)
Always statically link libc++ into our runtime and enable C++ exceptions, needed for future work. Additionally, transition from traditional C `printf` style logging to C++ [`std::format`][0]. The advantages are: * the format string is more expressive (doesn't require knowing the argument type, allows for positional placeholders as well as extra formatting specifiers, if needed), * safer (all arguments are type-checked at build time), and * faster (format strings are parsed and verified at build time, runtime involves only string rendering) Add a version script which hides all the symbols except for the handful we have to export. Remove C++ ABI compatibility sources. [0]: https://en.cppreference.com/w/cpp/utility/format/format
