MDEV-16191: Analyze format=json gives incorrect value for r_limit inside a dependent
...
subquery when ORDER BY is present
Currently for setting r_limit we divide with the number of iterations we invoke the dependent subquery.
This is not needed for the case of limit. For varying limits we produce the output that the limit varies with
execution.
Also there is a type for filtered , we forgot to multiply by 100 as it is represented as a percent.

MDEV-13826: Floating point exception in Filesort_tracker::print_json_members(Json_writer*)
...
Whenever Filesort_tracker has r_loops=0, r_ouptut_rows would be 0, so we should add the value zero
to the member "r_output_rows" explicitly
