boards/x86/acrn: build it in x86_64 mode and switch to X2APIC

ZideChen0 · andrewboie · commit d0126a037d23 · 2020-02-07T14:14:53.000-08:00
- added CONFIG_X86_64 since ACRN hypervisor supports x86_64 capable
  platforms only.
- removed CONFIG_SET_GDT: Zephyr doesn't support it in x86_64, and ACRN
  doesn't require the guests to setup GDT during boot time.
- added CONFIG_X2APIC, which is preferred by ACRN, which makes it
  possible to pass through local APIC to the guests.
