RFR: JDK-8300783: Consolidate byteswap implementations

Fri Jan 20 15:03:23 UTC 2023

Deduplicate byte swapping implementations by consolidating them into `utilities/byteswap.hpp`, following `std::byteswap` introduced in C++23. Further simplification of `Bytes` will follow in https://github.com/openjdk/jdk/pull/12078.
