Empty log queue on flush and close (#19994)
* Empty log queue on flush and close It is possible for log events to remain in the buffer off the multichannelledlog and thus not be logged despite close or flush. This PR simply adds a function to empty the queue before closing or flushing. (Except when the logger is paused.) Reference #19982 Signed-off-by: Andrew Thornton <art27@cantab.net> * and do similar for ChannelledLog Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
