kernel: smp: remove z_smp_thread_init/_swap

Browse source 
This removes z_smp_thread_init() and z_smp_thread_swap() as
SOF has been updated to use k_smp_cpu_custom_start() instead.
This removes the need for SOF to mirror part of the SMP
power up code, and thus these two functions are no longer
needed.
