zephyr: add notifier_register(ipc_send_queued_msg) in task_main_start() 

Fixes #4356

In XTOS SOF, ipc_send_queued_msg() is run by task_main_primary_core(),
the initialization of which has a hard and circular dependency with the
initialization of the EDF scheduler. This EDF scheduler is not part of
Zephyr. Because of the circular dependency it does not seem
possible (nor desirable?) to refactor this code and make it compatible
with Zephyr. So schedule ipc_send_queued_msg() differently in Zephyr:
using a notifier triggered by the periodic Low Latency scheduler.
