Add new config, ARCH_SUPPORTS_COREDUMP_THREADS, and
only enable it for ARM CORTEX M where the gdb server
can support it.

Add z_test which uses new configs to capture multiple
threads in a core dump and with all of the context
necessary to debug the threads.

Update core dump file format to support a new section which contains
metadata about threads necessary for debugging.
Define configs to capture that metadata and include it in the dumps
when enabled.
Update documentation to reflect the changes.

Do not enable subsystem/driver shell modules by default and stop abusing
CONFIG_SHELL_MINIMAL, which is internal to the shell subsystem, to decide
when to enable a driver shell.
The list of shell modules has grown considerably through the
years. Enabling CONFIG_SHELL for doing e.g. an interactive debug session
leads to a large number of shell modules also being enabled unless
explicitly disabled, which again leads to non-negligible increases in
RAM/ROM usage.
This commit attempts to establish a policy of subsystem/driver shell
modules being disabled by default, requiring the user/application to
explicitly enable only those needed.

Enabling the core dump via memory window backend only makes sense on
Intel ADSP platform wtih memory windows enabled.

The DEBUG_COREDUMP_BACKEND_LOGGING option should automatically
select LOG Kconfig instead of just depending on it.

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.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:
sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

Move coredump_backend_api struct to public header so that custom backends
for coredump can be defined out of tree. Create simple backend in test
directory for verification.

This adds some shell commands to the logging backend. Since
this is a simple backend, only get/clear errors are
implemented.

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.
