[vectorized](profile) fix pipeline profile can't get result under more instances (#18525)

Browse Source 
when enable pipeline to true, and set instances > 1
because all scan nodes share the scanners, maybe get the profile of scan node is all empty
now show all the scan nodes and remove some infos those that _num_scanners->value() == 0
