planner: add memory usage of analyze command in the result of "show analyze status"

## Enhancement
As the title say, now the result of "show analyze status" doesn't show the amount of memory it used, we'd better add this info into the result, which can help us investigate OOM or high-memory issues:
```
+--------------+------------+----------------+--------------------------------------------------------------------+----------------+---------------------+---------------------+----------+-------------+---------------------+------------+
| Table_schema | Table_name | Partition_name | Job_info | Processed_rows | Start_time | End_time | State | Fail_reason | Instance | Process_ID |
+--------------+------------+----------------+--------------------------------------------------------------------+----------------+---------------------+---------------------+----------+-------------+---------------------+------------+
| test | t | | analyze table all columns with 256 buckets, 500 topn, 1 samplerate | 1 | 2025-03-19 14:52:03 | 2025-03-19 14:52:03 | finished | NULL | 192.168.31.222:4000 | NULL |
+--------------+------------+----------------+--------------------------------------------------------------------+----------------+---------------------+---------------------+----------+-------------+---------------------+------------+
