zephyr: use z_init_cpu() if Zephyr 3.0.99 or newer

Use the new interface to initialize non-primary cores before
enabling them with arch_start_cpu(). This interface is not
available in Zephyr 3.0.0, but is mandatory in later release.

Depends on Zephyr commit 2b210cb3db05 ("kernel: Refactor SMP cpu
initialization a bit").
