* Update cxxstd values for GHA msvc jobs * Add msvc support for [[maybe_unused]] attribute. Fixes: https://github.com/boostorg/serialization/issues/271 Also removes failing cuda+clang test as it's an inscrutable system setup issue. * Add C++23 header macros. * Minor corrections. * Remove XCode-9.4 testing as it appears to be no longer supported. * Update docs for C++23 macros. [CI SKIP] * Add C++23 feature test macro support. * Use __apple_build_version__ to detect Apple clang …since __APPLE__ is defined by both Apple Clang and LLVM.org Clang on Apple platforms. * Update BOOST_CLANG_VERSION for Xcode 14.3, 15.0, 15.1 * Update CI clang version now that gcc has changed.
