[FEATURE] Implement module_init in Zephyr builds

[kv2019i]

Is your feature request related to a problem? Please describe.
With Zephyr builds, each module init needs to be called separately.

In XTOS builds we have:
• With XTOS builds, we use sof/src/include/sof/audio/component.h
#define DECLARE_MODULE(init) attribute((used))
» __section(".module_init") static void(*f##init)(void) = init
• And then sof/src/schedule/task.c:sys_module_init() makes the calls based on linker data

Describe the solution you'd like
Solution aligned with Zephyr where each module init call doesn't have to be added to wrapper.c
