cpu/x86/lapic: Support switching to X2APIC mode
The options X2APIC_ONLY and X2APIC_RUNTIME were already user-visible
choices in menuconfig, but the functionality was not actually provided
except for platforms where FSP presumably enabled X2APIC.
Add the logic and related logging for switching to X2APIC operation.
TEST: qemu-system-x86_64 -M Q35 -accel kvm -bios coreboot.rom -serial
stdio -smp 2
PARALLEL_MP, and either X2APIC_ONLY or X2APIC_RUNTIME, need to be
selected for the build of emulation/qemu-q35.
