cpuidle: haltpoll: Only define guest_halt_poll_ns tracepoint when used
Tracepoints that are defined take up around 5K each, even if they are not
used. When a tracepoint is used only in code when a specific config is
enabled, their definition must also be only defined when the same config
is enabled otherwise it wastes memory.
The tracepoint guest_halt_poll_ns is only used when CONFIG_CPU_IDLE_GOV_HALTPOLL
is enabled. Guard the definition of that tracepoint with the same config.
