MDEV-6137 better help for SET/ENUM sysvars

Browse Source 
Auto-generate the allowed list of values for enum/set/flagset options
in --help output. But don't do that when the help text already has them.

Also, remove lists of values from help strings of various options, where
they were simply listed without any additional information.
