Mark Holden 8bd4f244b0 coredump: ARM: Ensure sp in dump is set as gdb expects
Gdb is typically able to reconstruct the first two frames of the
failing stack using the "pc" and "lr" registers. After that, (if
the frame pointer is omitted) it appears to need the stack pointer
(sp register) to point to the top of the stack before a fatal
error occurred.

The ARM Cortex-M processors push registers r0-r3, r12, LR,
{possibly FPU registers}, PC, SPSR onto the stack before entering the
exception handler. We adjust the stack pointer back to the point
before these registers were pushed for preservation in the dump.

During k_oops/k_panic, the sp wasn't stored in the core dump at all.
Apply similar logic to store it when failures occur in that path.

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`_.
