MDEV-24920: Merge "old" SQL variable to "old_mode" sql variablebb-10.7-MDEV-24920
Analysis: There are 2 server variables- "old_mode" and "old". "old" is no
longer needed as "old_mode" has replaced it (however still used in some places
in the code). "old_mode" and "old" has same purpose- emulate behavior from
previous MariaDB versions. So they can be merged to avoid confusion.
Fix: Deprecate "old" variable and create another mode for @@old_mode to mimic
behavior of previous "old" variable. Create specific modes for specifix task
that --old sql variable was doing earlier and use the new modes instead.
