Refactor Apple SoC detection

Dr-Noob commented 6 months ago

guess_soc_apple and get_cpu_info_mach need refactoring since they'll probably keep releasing more and more chips. Also asahilinux has a very good tracking of the MIDR values which we should replicate since currently we are setting the same MIDR for all CPU types within a family (M1/M2/M3) which is incorrect. Instead we should follow this.

Also fix this: // Must be M1 in src/arm/midr.c

Also fill_cpu_info_XXX_XXX is not maintainable.

Even more neccesary after d221f578b79b40ffbb3284f61a62bc1de36bbb84

BTW: since I had an aarch64 Linux VM running on my MacBook below the output. Wouldn't it be an idea to print Virtualized Apple Silicon in such situations?

Apple's Hypervisor.Framework limits CPU features/flags to the one of M1's cores and sets the stepping info to r0p0 on all cores regardless of their real stepping. So it should be easy to detect such an environment?
