Sometimes, `show load profile` will only show part of the insert opertion's profile.
This is because we assume that for all load operation(including insert), there is only one fragment in the plan.
But actually, there will be more than 1 fragment in plan. eg:
`insert into tbl1 select * from tbl1 limit 1` will have 2 fragments.
This PR mainly changes:
1. modify the `show load profile`
Before: `show load profile "/queryid/taskid/instanceid";`
After: `show load profile "/queryid/taskid/fragmentid/instanceid";`
2. Modify the display of `ReadColumns` in OlapScanNode
Because for wide table, the line of `ReadColumns` may be too long for show in profile.
So I wrap it and each line contains at most 10 columns names.
3. Fix tvf not working with pipeline engine, follow up #18376
