For some reason, running sys-t with catalog message on
Cortex-M0 would result in hard fault in mipi_catalog_formatter()
if log_output_syst.c is complied before the backends (and weird
enough, only with SIZE optimization). This new ordering was
introduced in commit f5587552bb
as it was to group all backend source files under a single
directory.
Workaround the issue by compiling file later after backends
as this issue is causing CI failures. Actual root-cause is TBD.

To enable custom formatting of the log output while still using existing
backend, this commit adds the `log_output_custom` feature.
To use, register a commit with `log_custom_output_msg_set` then set the
log backend format set using `log_backend_format_set` with
`LOG_OUTPUT_CUSTOM`

to relay log messages over SRAM. This protocol is implemented
by the SOF Linux driver ("mtrace" debugfs interface).
This implementation follows example of the ADSP HDA logger implemented

Logging v2 is utilizing complex preprocessing operations to
prepare message at compile time. Multiple operations are peformed
on log message arguments. However, it is expected that argument
will be evaluated only once (e.g. it can be a call to a function
with side effects). Adding additional layer which creates copies
of user arguments on stack and passes them to further processing.
Updated test for log_msg2 which is using internal macro which
got renamed.

Reduced logging mode selection to deferred, immediate, minimal and
frontend. Decoupled logging version from mode and created CONFIG_LOG1
which can be used to explicitly select deprecated version.

in version2.

Remove LOG_MINIMAL kconfig option which was confusing
since LOG_MODE_MINIMAL existed. LOG_MINIMAL was used to
force minimal mode but because of invalid dependencies
it was leading to issues.
Refactored code to use LOG_MODE_MINIMAL everywhere and
renamed LOG_MINIMAL to LOG_DEFAULT_MINIMAL which has impact
on defualt logging mode (which still can be later changed
in conf file or in menuconfig).

The log mechanism, even in immediate mode, adds somewhere
between 1K-2K of footprint to applications that use it.
We want to standardize the logging APIs for all logging
within the kernel, but need to not let platforms with
very constrained RAM/ROM in the dust.
This patch introduces CONFIG_LOG_MINIMAL, which is a very
thin wrapper to printk(). It supports the APIs expressed
in logging/log.h.
This will be the new default for test cases.
