### Rationale for this change We decided to migrate Arrow C++ to C++20 in this discussion: https://lists.apache.org/thread/48zlj0dn2y0f53y2k37qsr90y781wfnj ### What changes are included in this PR? 1. Build configuration updates (CMake files etc.) to build with C++20 instead of C++17 2. C++-level fixes to ensure compilation succeeds: * Workarounds for deprecation of atomic access on `std::shared_ptr<T>` (the replacement `std::atomic<std::shared_ptr<T>>` is unfortunately not supported in all standard library implementations) * Workaround for [Abseil ABI issues](https://github.com/abseil/abseil-cpp/issues/1624) * Trivial update to `arrow/util/string.h` to call a C++20 API (to validate that C++20 is actually enabled) 3. CI configuration updates to get enough C++20 support on the various platforms: * Bump default clang and LLVM versions to 18 * Use AlmaLinux 10 for release verification (AlmaLinux 8 is still tested on other CI builds) ### Are these changes tested? Yes. ### Are there any user-facing changes? Yes, Arrow C++ will now require a C++20-compliant compiler. * GitHub Issue: #45885 Authored-by: Antoine Pitrou <antoine@python.org> Signed-off-by: Antoine Pitrou <antoine@python.org>
