log: Allow LOG_DEBUG to always enable log output
At present if CONFIG_LOG enabled, putting LOG_DEBUG at the top of a file
(before log.h inclusion) causes _log() to be executed for every log()
call, regardless of the build- or run-time logging level.
However there is no guarantee that the log record will actually be
displayed. If the current log level is lower than LOGL_DEBUG then it will
not be.
Add a way to signal that the log record should always be displayed and
update log_passes_filters() to handle this.
With the new behaviour, log_debug() will always log if LOG_DEBUG is
enabled.
Move log_test_syslog_nodebug() into its own file since it cannot be made
to work where it is, with LOG_DEBUG defined.
