Introduce `CpuId::current()`, a constructor that wraps the C function
`raw_smp_processor_id()` to retrieve the current CPU identifier without
guaranteeing stability.
This function should be used only when the caller can ensure that
the CPU ID won't change unexpectedly due to preemption or migration.
