dd38a2ccde logging: Fix string stripping Kconfig option dependency
Change to depend on LOG_DICTIONARY_DB which is broader than
LOG_DICTIONARY_SUPPORT which is set only when log_output
supports dictionary mode. However, it is possible that
log_output is not used when dictionary mode is used. Database
generation is always enabled when dictionary mode is used.

67403ed73d logging: Do not strip strings when LOG_OUTPUT is used
When CONFIG_LOG_OUTPUT is enabled that indicates that logging
strings are used by the runtime logging processing so they should
not be stripped from the binary.

cb0a3ce6aa logging: dictionary: keep string section if always runtime
If logging packages need to be created at runtime, the format
strings need to be in memory for the packaging code to know
what to be packed. So prevent stripping the logging string
section if CONFIG_LOG_ALWAYS_RUNTIME is enabled.

ad58b39f41 logging: Add option to not generate dictionary database always
Add option to not generate the logging dictionary database when the
zephyr finale image is created. Instead this database can be created
by its own build target.
This reduces the build time during debugging as the database file is not
required as part of the debugging.

Fix build byproducts not listing the output file.
Add comment so users know which command is executing as this command
can take a long time.

b9bf596b34 logging: Fix LOG_FMT_SECTION_STRIP Kconfig dependency
Strings stripping was disallowed when LOG_OUTPUT was used. However,
there is a dictionary log_output module which could work with stripped
strings. Dependency is changed to LOG_DICTIONARY_SUPPORT.

465446e5aa logging: Add string validation to detect %p misuse
Logging shall not use character pointers with %p because in
certain configurations it may lead to memory faults. A compile
time detection is added. If faulty usage is detected then
message is replaced with error message which indicates which
message failed and what shall be done (casting to a pointer
of different type).

Validation is enabled only for configurations which remove
strings from binary as otherwise it may impact CI execution
time.

c0c8952739 shell: do not enable subsystem/driver shell modules by default
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.

a68cdb0558 logging: Optimize handling of simple and common log messages
Some compilers (e.g. riscv32) does not handle well complex macros
for logging. Generated code is bigger than expected (e.g. riscv32
code is almost twice bigger than cortex-m code). Use of logging can
lead to unexpected code increase.

To handle that an analysis of the zephyr code base was performed and
it shown that 75-80% of logs are simple strings with 0 arguments
(~45%), one 32 bit argument (~26%) or two 32 bit arguments (~6%).
Given that a set of dedicated macro were created which are applied
to those 3 cases which on 32 bit platform create very simple log
messages without padding or alignment needed.

Such dedicated macros save up to 40% of code (riscv32) and also
executes 30% faster (arm cortex and riscv32).

fe0aa4c167 logging: support tagged argument in log message packaging
This adds support for packaging with tagged arguments for log
messages so that backends can make use of this information
when they process messages.

Note that currently tagged arguments must be used with
CONFIG_LOG2_ALWAYS_RUNTIME where log messages are created via
z_log_msg2_runtime_{v,}create(). For some reason, using C++ on
Cortex-M (mps2_an385) results in an additional empty string
argument being added to the list. This does not happen if only
doing C on mps2_an385, or on other architectures.

c0808e3f59 logging: Minimal mode configuration cleanup
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).
