Bugfixes

• Fix fallback to x86_64h-apple-darwin on aarch64-apple-darwin: Now it only fallbacks if arch -arch x86_64h /usr/bin/true success since Rosetta 2 doesn't support AVX yet (x86_64h-apple-darwin failed to execute on my M1 #1277 Fix aarch64-apple-darwin fallback to x86_64h #1278)
• Fix our universal-apple-darwin pre-built listed below for pre-haswell Intel CPUs (x86_64h-apple-darwin failed to execute on my M1 #1277 Include x86_64 & x86_64h in universal apple pre-built binary #1279)
• Fix our installation script and the action on MacOS: Since it users our universal binary by default and the GHA MacOS runner uses pre-haswell Intel CPU, it will fail due to bad cpu type (x86_64h-apple-darwin failed to execute on my M1 #1277 Include x86_64 & x86_64h in universal apple pre-built binary #1279)
