executor: arm64: store CPU ID in TPIDR_EL1
Let SYZOS distinguish CPUs inside VM by storing their ID in TPIDR_EL1.
Make sure existing code uses that ID:
- in guest_handle_msr(), to ensure concurrent calls do not write to the
same cache line;
- in gicv3_irq_enable(), to ensure proper CPU ID is being used for
IRQ setup.
