Various code assumed this was true already, and usually it is. However, it emerges that in a "universal" (multi-architecture) macOS build, configure will define USE_AVX2_WITH_RUNTIME_CHECK if the build host is x86_64, and then the arm64 half of the build fails. Ideally we'd get pg_config.h to define this symbol conditionally depending on defined(__x86_64__), but I don't see any way to persuade Autoconf to do that. Instead, clean up the mess by #undef'ing it again in c.h for not-x86_64 builds. For consistency I made c.h also #undef the USE_AVX512... symbols. Those are not actively broken, but it seems only happenstance that configure's tests for them fail in a universal build. Down the road we may have occasion to add more #undef's here. This problem is new in v19, so no need for back-patch.
