boot/efi/x86: implement SMP detection and bootup

* move common SMP initialization code to x86/arch_smp.cpp

* factor out arch-specific SMP initialization to
  arch_smp_32.cpp resp arch_smp_64.cpp

* implement smp_trampoline for x86 32-bit EFI loader

* rename SMP trampoline for x86_64 to long_smp_trampoline

* add new argument virtKernelArgs to arch_smp_boot_other_cpus
  as the kernel args are not identity mapped on 32-bit architectures
