[feature](Nereids) enable bucket shuffle join on fragment without scan node

[morrySnow]

Proposed changes

In the past, with legacy planner, we could only do bucket shuffle join on the join node belonging to the fragment with at least one scan node.
But, bucket shuffle join should do on each join node that left child's data distribution satisfy join's demand.
In nereids, we have data distribution info on each node. So we could enable bucket shuffle join on fragment without scan node.
