arch: x86_64: re-enable -mno-red-zone

Red zone was causing issues in places where inline assembly was pushing
data to stack, like arch_irq_lock, and possibly in other places.
Initially -mno-red-zone was enabled on x86_64, but was later, maybe
accidentially, disabled in https://github.com/zephyrproject-rtos/zephyr/
