Add support to coredump_gdbserver.py for running in a pipeline,
communicating through stdin/stdout instead of a socket.
This allows starting it from inside gdb, with:
target remote | coredump_gdbserver.py --pipe <elf_file> <log_file>

This adds support for using coredump with Xtensa DC233C core,
which are being used by qemu_xtensa and qemu_xtensa_mmu.

The current toolchain version for espressif SoCs does not
have the same limitation on registers indexing as the previous
one, enabling sending the correct A0-A15 register values directly

Disables allowing the python argparse library from automatically
shortening command line arguments, this prevents issues whereby
a new command is added and code that wrongly uses the shortened
command of an existing argument which is the same as the new
command being added will silently change script behaviour.

Adds compatibility with Intel ADSP GDB from Zephyr SDK and
from Cadence toolchain to coredump_gdbserver.py.
Adds CAVS 15-25 (APL) register definitions. Implements
handle_register_single_read_packet to serve ADSP GDB
p packets.
Prevents BSA from changing between stack dump printout
and coredump by taking lock. Observed to be necessary for
accurate results on slower simulated platforms.

Adjust get_mem_region to not return region when address == end
as there will be nothing to read there. Also, a subsequent region
may have that address as a start address and would be a more appropriate
selection.

GDB server dummies WINDOWBASE to 0 and WINDOWSTART to 1
for both arches and sends An as corresponding ARn for ESP32
to get around packet size limitation. Fixes backtrace and
other issues causing GDB client to crash.

The parser module name collides with builtin parser module in python.
This seems to break the import in windows.

This removes the z_ prefix those (functions, enums, etc.) that
are being used outside the coredump subsys. This aligns better
with the naming convention.

get_mem_region() may return None for a non-existent memory region
so we need to check first before looking at its properties.

This adds the necessary bits in arch code, and Python scripts
to enable coredump support for ARM Cortex-M.

This adds a very primitive coredump mechanism under subsys/debug
where during fatal error, register and memory content can be
dumped to coredump backend. One such backend utilizing log
module for output is included. Once the coredump log is converted
to a binary file, it can be used with the ELF output file as
inputs to an overly simplified implementation of a GDB server.
This GDB server can be attached via the target remote command of
GDB and will be serving register and memory content. This allows
using GDB to examine stack and memory where the fatal error
occurred.
