Peter Mitsis 9ff5221d23 kernel: Update IPI usage in k_thread_priority_set()
1. The flagging of IPIs is moved out of k_thread_priority_set() into
z_thread_prio_set(). This allows for an IPI to be done for a thread
that had its priority bumped due to the handling of priority
inheritance from a mutex.

2. k_thread_priority_set()'s check for sched_locked only applies to
non-SMP builds that are using the old arch_swap() framework to switch
between threads.

Incidentally, nearly all calls to flag_ipi() are now performed with
sched_spinlock being locked. The only exception is in slice_timeout().

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
