This code is meant to run in the context of a exception.
Most architectures will fail the asertion made in z_impl_k_sem_take()
when timeout is not K_NO_WAIT.
This commit ensures K_NO_WAIT is used when arch_is_in_isr() is true.

The buffer_output interface is called a few times during one core dump,
so we need to maintain a memory write pointer to prevent data overwriting.

For debug usage is added backend for memory window.
Coredump is being dumped in raw data. It needs to be converted to
ACSII for later analysis. Data is written to telemetry slot
in memory window which is a space where is located all debbug
information.

MISRA Rule 5.7 requires uniqueness of tag identifiers. Shell is
frequently problematic because many code uses `const struct shell
*shell`. This causes CI noise every time one of these shell files is
edited, so let's update all of them with `const struct shell *sh`
instead.

The commit switches flash area access from FLASH_AREA_ macros
to FIXED_PARTITION_ macros and to usage of DTS node labels,
to identify partitions, instead of label property.

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.

Add a pseudo device diver with device tree bindings for coredump.
The device tree bindings exposes memory address/size values to be
included in any dump. And the driver exposes an API to add/remove
dump memory regions at runtime.

If CONFIG_STREAM_FLASH_ERASE is set, a page erase is done before
writing the coredump header to the flash. If the flash page erase size
is larger than the flash write size this results in erasing part of
the coredump data.

This removes the z_ prefix those (functions, enums, etc.) that

This adds some shell commands to the logging backend. Since

This adds two new APIs to the coredump subsystem to perform
query and command. These can be used to query coredump subsys
for information, and to perform commands such as finding
out if there is a stored coredump.

The coredump frontend (mostly) consists of wrappers of backend
functions so there is really no need to track errors at
the frontend level. Let the backends deal with their own errors
and this simplifies the code a bit.

Originally there was a null backend but it was removed before
code was merged. However, some leftover code still refers to
this null backend. So remove the leftovers.

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.
