MDEV-27021 Add explicit indication of SHOW EXPLAIN/ANALYZE.

Browse Source 
1. Add explicit indication that the output is produced by
SHOW EXPLAIN/ANALYZE FORMAT=JSON command.
2. Remove useless "r_total_time_ms" field from SHOW ANALYZE FORMAT=JSON
output when there is no timed statistics gathered.
3. Add "r_query_time_in_progress_ms" to the output of SHOW ANALYZE FORMAT=JSON.
