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`

Adding mechanism to all the backends to switch the logging formats
at runtime while leveraging the function pointer table based upon
the Kconfigs which also cleans up the logging backend design.
Also demonstrate the working API with the changes
to syst sample. Clean up Kconfig for backends and add a standard
template to generate the Kconfigs for logging formats to be used
by all backends.
