Some test cases where impacted:
* ps_missed_cmds{,_bin_prot} - used a topic_id of 0 that is
now used, used MAX_INT instead.
* range_notembedded used the help data as a test case. As its not
a stable table data, replaces with static data. Test case valid
by ensuring the ANALYZE EXPLAIN and optimizer trace had the same
structure. Also valided the MDEV-24739/MDEV-25069 bug fixes from
where the test case originaled, when reverted, exhibited the
previous behavour before the bug fixes.
