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.

Justin King has updated the pull request incrementally with one additional commit since the last revision: Consolidate more byteswap implementations and upgrade bit reversal Signed-off-by: Justin King <jcking@google.com> ------------- Changes: - all: https://git.openjdk.org/jdk/pull/12114/files - new: https://git.openjdk.org/jdk/pull/12114/files/f6996e1a..56e5c235 Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=12114&range=08 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=12114&range=07-08 Stats: 196 lines in 3 files changed: 97 ins; 25 del; 74 mod Patch: https://git.openjdk.org/jdk/pull/12114.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12114/head:pull/12114 PR: https://git.openjdk.org/jdk/pull/12114
