[enhancement](stream load pipe) using queryid or load id to identify stream load pipe instead of fragment instance id

[yiguolei]

Proposed changes

NewLoadStreamMgr already has pipe and other info. Do not need save the pipe into fragment state. and FragmentState should be more clear.

But this pr will change the behaviour of BE. I will pick the pr to doris 1.2.3 and add the load id to FE support. The user could upgrade from 1.2.3 to 2.x
