- Leveraged autoconf again to check whether the C++ compiler supports the required standard version and build using it. - Replaced the outdaded `ax_cxx_compile_stdcxx_11.m4` macro with the latest version of `ax_cxx_compile_stdcxx` which supports C++17. - https://www.gnu.org/software/autoconf-archive/ax_cxx_compile_stdcxx.html - https://raw.githubusercontent.com/autoconf-archive/autoconf-archive/e4e5269db2764b9f53d759c24750ac6ca38e02ea/m4/ax_cxx_compile_stdcxx.m4 - This should also streamline updating to C++20 in the future.

what
Leveraged autoconf again to check whether the C++ compiler supports the required standard version and build using it.
why
Simplify std C++ used to build libModSecurity codebase to minimize configuration that depends on this setting.
This streamlines updating to C++20 in the future as it needs to be changed in a single place.
changes
