#13004 changed the default behavior for -printtoconsole but this has not been reflected in the command line help.
This fixes the description of -printtoconsole to reflect this change, and also provides the user with missing information on how to explicitly disable logging to debug.log.
At present I have made the latter update to two separate places (-printtoconsole and -debuglogfile) because a user looking for information on how to disable logging is probably going to look in the "Debugging/Testing Options" section. Moving -debuglogfile from the "General" options category to the "Debugging/Testing" section could potentially remove the need for this redundancy, but is probably out of the scope of this PR.
