Three small source tweaks that let the OpenGL renderer build and run on Apple Silicon without affecting the Windows/Linux paths: - stdafx.h: use GLM_FORCE_NEON on ARM64 instead of GLM_FORCE_AVX2. AVX2 pulls <immintrin.h>, which clang on ARM64 rejects because the x86 intrinsics are unimplemented. - utilities/utilities.cpp: provide an Apple libc++ fallback for Now() using localtime_r + strftime, since std::chrono::current_zone() is not yet implemented there. - audio/audio.h: prefer Khronos-style <AL/al.h> headers when they are on the include path (brew openal-soft) and fall back to the deprecated Apple OpenAL.framework's <OpenAL/al.h> only otherwise.
