[FEATURE][Zephyr] Implement arch_cpu_disable_core and cpu_power_down_core in wrapper.c #5094
Description
Is your feature request related to a problem? Please describe.
Currently secondary cores are only powered down when DSP is put to suspend, or via out-of-band means (on Intel cAVS1.5, host controls power directly for the DSP cores).
Zephyr now implements interface to start/stop xtensa cores, so this should be used in wrapper.c.

We need to start using native Zephyr APIs and wrap the xtos version of these functions.

Implemented with #5298 .
The native interface will be a Zephyr replacement of SOF runtime PM for DSP cores.
