Get TSC frequency from CPUID 0x15 and/or x16 for newer Intel processors. - If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors can take TSC/core crystal clock ratio but core crystal clock frequency can't be taken. Intel SDM give us the values for some processors. - It also required to change lapic_per_second to make LAPIC timer correctly. - Add new file x86/x86/identcpu_subr.c to share common subroutines between kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c will be moved to this file in future. - Add comment to clarify.

PR port-amd64/37461 x86 cpu dmesg output is noisy Port identifycpu() to userspace. The kernel lies and reports on cpuN while actually using the values from cpu0, but this attempts to bind itself to the requested CPU if running as root. That doesn't work properly yet due to kern/38588, but will do once that's fixed.

Add cpuctl(8). For now this is not much more than a toy for debugging and benchmarking that allows taking CPUs online/offline.

Remove 3rd buggy copy of this function and use snprintb(3) instead. No need to allocate MAXPATHLEN buffers anymore.
