logging: move backends to subdirectory This is mainly to reduce clutter in `subsys/logging`, but also to make backend management slightly easier. Signed-off-by: Christopher Friedt <cfriedt@fb.com>

logging: allow OOT backend to enable LOG_BACKEND_FORMAT_TIMESTAMP The `LOG_BACKEND_FORMAT_TIMESTAMP` Kconfig currently depends on a list of hardcoded backends. Let's modify it to depend on an intermediary Kconfig `LOG_BACKEND_SUPPORTS_FORMAT_TIMESTAMP` instead, which can be selected by a OOT log backend. Updated all exisitng supported backends to select this new Kconfig. Signed-off-by: Yong Cong Sin <ycsin@meta.com>

help
When enabled, backend is using the configured file system to output logs.
As the file system must be mounted for the logging to work, it must be
either configured for auto-mount or manually mounted by the application.
Log messages are discarded as long as the file system is not mounted.

logging: log_backend_fs: added LOG_BACKEND_FS_AUTOSTART configuration This configuration option gives the possibility to not enable the fs backend on startup. Backend can be enabled in runtime using log_backend_init and log_backend_enable functions. Implementation is based on log_backend_net. Signed-off-by: Wojciech Slenska <wsl@trackunit.com>

application start.

config LOG_BACKEND_FS_OVERWRITE
bool "Old log files overwrite"
default y
help
When enabled backend overwrites oldest log files.
In other case, when memory is full, new messages are dropped.
logging: fs backend: optional append to latest file Make appending to the newest log file in the fs logging backend optional. By default, if there is still free space in the latest log file, the fs logging backend appends to it on startup. This is useful for saving space and avoiding the removal of older log files, if the maximum number of log files has been reached. The drawback of this behavior is, that log files that got appended can not be decoded, if the firmware has changed between startups, for instance by an update, since the log_dictionary.json used for decoding has also changed. Therefore, it may be desirable to deactivate appending to log files. Signed-off-by: Niklas Fabian <niklas.fabian@lemonbeat.com>

config LOG_BACKEND_FS_APPEND_TO_NEWEST_FILE
bool "Append to the newest log file"
default y
help
When enabled and when there is space left in the newest log file,
backend appends to it.
When disabled backend creates a new log file on every startup.
