Summary
Add support for legacy xAPIC alongside x2APIC.
This way we can run nuttx x86_64 on qemu without the --enable-kvm option
Impact
nuttx x86_64 works on old qemu and can work without the --enable-kvm option
Testing
NSH boots in nuttx CI docker container that use old QEMU version without x2APIC support
