Use standard C23 and C++ attributes if available Use the standard C23 and C++ attributes [[nodiscard]], [[noreturn]], and [[maybe_unused]], if available.
This makes pg_nodiscard and pg_attribute_unused() available in not-GCC-compatible compilers that support C23 as well as in C++. For pg_noreturn, we can now drop the GCC-specific and MSVC-specific fallbacks, because the C11 and the C++ implementation will now cover all required cases. Note, in a few places, we need to change the position of the attribute because it's not valid in that place in C23.
